Police have arrested a Somalian man on suspicion of murdering the Conservative MP Sir David Amess, who was stabbed multiple times at his constituency surgery.
Sir David, the MP for Southend West in Essex, was attacked on Friday at Belfairs Methodist Church in Leigh-on-Sea.
Paramedics tried for two hours to save the 69-year-old father-of-five, but he died of his injuries and figures across the political spectrum have paid tribute to the "irreplaceable" MP.
Essex Police said counter-terror officers were leading the investigation after a 25-year-old man was arrested, and officers were not looking for anybody else in connection with the incident.
A witness who described seeing the suspect being taken away by the police said he was calm and compliant.
Security sources confirmed that the suspect was believed to be a Somalian, but police were still seeking to establish a motive for the attack.
Ben-Julian Harrington, Chief Constable Essex Police: "It will be for investigators to determine whether or not this is a terrorist incident."

Jess Phillips: 'I genuinely can’t think of a bad word to say about him'
Our reporter Max Stephens is at the Cheltenham Literature Festival where MP Jess Phillips is promoting her book 'everything you really need to know about politics, my life as an MP'.
She said: "I genuinely can’t think of a bad word to say about him, and that is not the case of lots of my colleagues from all sides of the house.
"He was just a nice and really friendly man.
"Why anybody would want to attack somebody like this I have no idea, but then there is no rhyme or reason to it.
“But the way it makes me feel as a Member of Parliament it’s a sort of blankness, I don’t know how to feel or process it.
“It brings back horrendous memories of the same feeling when my friend Jo Cox was shot and killed.
"And it is a mixture of shock and genuine shock that just blanks you out.
"I have had about 700 messages from journalists and newscasters since it happened and it was announced literally an hour ago that he had died.
"I don’t have the space in my brain to think about the big implications to our democracy of these things or what the solutions are to what possibly could have gone wrong in this case.
"It’s just shock, I feel very very shocked and you have to try and not let that quiet shock turn into despair or immediately risk assess everything.

'He was a devout and devoted man, he was the kindest of people'
Sir Roger Gale, who entered the Commons alongside Sir David Amess in the 1983 General Election, told Sky News how his friend was "funny, fun, dedicated and determined' and "never too serious but always serious at the right time" which was why he was "such an effective Member of Parliament". Watch the clip below.
'He was funny, fun, dedicated and never too serious... His work will go on.'
MP Sir Roger Gale, friend of Sir David Amess, pays tribute to the Conservative MP after he died following a stabbing attack.
Meanwhile, Defra minister Victoria Prentis shared a playful picture of the MP, saying that "no one could have done more for his constituents", referencing his campaign to have Southend recognised as a city, as well as work on less fashionable issues.
Sir David Amess was the best of MPs and a dear friend. No one could have done more for his constituents. We all know that Southend should be a city. The issues he spoke about were not always fashionable; but those with endometriosis, refugees, and animals in him found a voice. pic.twitter.com/ARsqxLgywp
Sir David Amess has been remembered as "Mr Southend" at a vigil held in his memory.
Born in east London, the 69-year-old had been Southend West MP since 1997 - and was a keen advocate of the town's bid for city status.
A service at Saint Peter's Church in Eastwood Lane, close to where Sir David was killed, was held on Friday evening to remember him - where he was described by a priest as "Mr Southend".
The church fell silent as Father Jeffrey Woolnaugh paid tribute to the Conservative MP and invited his constituents to remember him.
He placed a photograph of Sir David at the front of the church, and said: "This liturgy is one I was not expecting to lead today.
"The whole world grieves. In this Mass we pray for the repose of the soul of dear David.
"Have you ever known Sir David Amess without that happy smile on his face? Because the greeting he would always give you was that happy smile.
"He carried that great east London spirit of having no fear and being able to talk to people and the level they're at. Not all politicians, I would say, are good at that."
Around 80 people attended the service and listened as Father Woolnough recounted his own memories of Sir David.
He said: "When you can speak to your MP and you can talk and get on like a house on fire, that's when you can talk to them later about things that are important to your area.
"What can we say? He died doing the thing he loved, meeting his constituents, his local people."
Father Woolnough added that his constituents could "count on" Sir David, and said: "He was always available. We don't have the words tonight.
"Dear Sir David, rest well."
Those who attended the vigil were invited to light a candle and share their own memories of Sir David. A lone candle placed outside the church burned as the Tory MP's constituents remembered him.

Reaction from man who Sir David gave first graduate job to
A government speechwriter has told how Sir David Amess MP gave him his first graduate job.
Ed Holmes, who works for the Department for International Trade, said: "Sir David Amess MP gave me my first proper job after university.
"Early on, I was absolutely terrified we had forgotten to tell him about an urgent call from David Cameron's office.
"Couldn't have bothered him less 'don't worry about that, Edward'. I don't think he ever returned it.
"That week his invitation to a local charity event in the constituency - the Leigh Duck race - went missing.
"Nothing was more important. We spent the entire afternoon turning the office upside down trying to find it.
"Another time I took a message from the Whips Office for him to call them.
"They said if David voted the right way on a piece of legislation, they would consider him for a ministerial role.
"When I told him, David just laughed (I don't think he ever returned that call either).
"But when he heard someone he knew in the constituency was seriously ill, he would call everyone he could think of.
"I remember listening to him late into the evening on the phone to some of the most senior medics in the land- nagging, cajoling, pleading for them to intervene.
"Even when they were clearly fed up of him- and even when it was clearly a hopeless case - David never stopped trying.
"No votes to be had, no cameras in sight. I think that's when I admired him the most.
"No MP could have been clearer about putting the needs of his constituents first - before party, ambition and everything else - than Sir David.
"My thoughts with Julia and his family at this dreadful time."

Essex Police statement, in full
Just after midday, Essex Police were called to reports of a stabbing in Eastwood Road North in Leigh-on-sea.
The response from the emergency services to this incident was immediate and our officers arrived on scene within minutes.
When they arrived, they found Sir David Amess MP who had suffered multiple injuries.
This was a difficult incident, but our officers and paramedics worked extremely hard to save Sir David.
Tragically, he died at the scene.
A 25-year-old man was arrested immediately at the scene on suspicion of murder.
He remains in custody.
A knife was also recovered at the scene.
The investigation is in its very early stages and is being led by officers from the specialist counter-terrorism command.
We made it clear at the time of the incident that we did not believe there was any immediate further threat to anybody else in the area.
It will be for investigators to determine whether or not this is a terrorist incident.
But, as always, they will keep an open mind.
Today is a tragic day for the family and colleagues of Sir David, the community of Southend and indeed for the whole of greater Essex.
Sir David has dedicated his life to serving the communities of Essex and Southend and today he was simply dispensing his duties when his life was horrifically cut short.
I know the residents of Essex and Southend West will stand with me today in remembering a member of our community.
Here at Essex Police, officers right across our force - and particularly in Southend - have enjoyed a longstanding and positive working relationship with Sir David.
And today's events will be hard to take for everyone who knew him.
Specially-trained family liaison officers are offering support to his family today.
Our officers will continue to work around the clock to ensure justice is delivered for Sir David and his family, and I'd like to thank the people of Southend for their understanding as the investigation continues.
I would urge anyone who has any information in relation to this terrible incident to call Essex Police on 101, online or via Crimestoppers.
Finally, I ask for everybody to respect the privacy of Sir David's family at this really difficult time and to say my personal thoughts having worked with Sir David and of course from all those from Essex Police and our prayers are with Sir David and his family at this difficult time.

John Bercow: 'There is much toxicity in our politics'
The former Speaker of the House of Commons, John Bercow, has described Sir David Amess as "an outstanding member of parliament”, warning “there is much toxicity in our politics".
Speaking to BBC Radio 4’s PM programme, he said: "He was an outstanding member of parliament, but he was also a loving and much loved human being.
"Conscientious, assiduous, dutiful, caring, passionate, principled … He was an indefatigable campaigner for what he believed to be right… and above all he was quintessentially a constituency parliamentarian.
"He could talk to and hear from and engage with anybody, from a monarch to the local milk person. He was a wonderful loving human being and we rue his loss.”
The former Speaker, who left his post in 2019, also said that ‘there is much toxicity in our politics’.
"Huge numbers of people are people of goodwill, and the vast majority of people -- almost without exception-- would deplore and deprecate in the strongest possible terms this gross and heinous act.
"It is an unspeakable barbarity. But the truth is there is much toxicity in our politics, and I think this should give us pause to think and reflect on how politics is conducted in the future and whether there are security improvements."

Sir David's approachability left him 'vulnerable', says local Tory councillor
David Garston, a local Conservative councillor, said Sir David Amess was an "irreplaceable" constituency MP whose approachability left him "vulnerable".
"He was probably one of the best constituency MPs in the country, and because he was so accessible and because he was everywhere, he obviously left himself vulnerable and didn't think twice about it," Mr Garston told the PA news agency.
The councillor said that when Sir David came to his ward, "you couldn't get very far because he'd stop every hundred yards to talk to somebody".
He said: "It was always very slow with Sir David but he's paid the price for being so easily got at unfortunately and I just think it's dreadful.
"The community have lost a really good MP who cared deeply for them and he'll be a very, very hard act to follow. To find an MP like Sir David, who didn't think about ministerial position - he wasn't interested, he was a community man - I would say he's irreplaceable."

Lord Eric Pickles says constituency surgeries 'is part of the job'
Lord Eric Pickles told Sky News: "Obviously it is terribly sad and tragic news. He was a great family man, a great local constituency mp somebody who cared deeply about ethics."
On constituency surgeries: "Friday mornings and Friday afternoons is a very common time for MPs to have their constituency surgeries. I used to hold mine on a Friday.
He said: "I used to like to know who was coming to mine," adding that, "if you are being really really blunt sometimes it [the surgeries] attracts obsessives and you need to have a degree of circumspection."
Face-to-face constituencies had only recently resumed. When asked if we needed to have a discussion again about MPs security, he replied: "No, it is part of the job. It is something you sign up to. "
He added: "Part of David's accessibility was one of the reasons he was such an effective operator inside parliament and inside politics."
When pressed on the "it is part of the job" comment and what it says about society, he said: "It is tragic, it is dreadful but it is not normal. That terrible attack on Stephen Timm which pleasingly had a happier outcome. It happens and it may be that MPs may take the basic precautions of getting a name and an address before they see somebody or getting the outline of a case before they see somebody."
He added: "When you’re dealing with people who are very emotional, who feel like the system has let down, often they’re looking for someone to blame. But if we close up shop, and disappear behind a security bubble, then it’s democracy itself that’ll be the lesser thing.”

Amess stabbing latest attack on MPs in their constituencies
The stabbing of Conservative MP Sir David Amess is the latest attack on MPs in their constituencies, including the murder of Jo Cox.
The country was rocked when the 41-year-old Labour MP for Batley and Spen was shot and stabbed in her constituency by a far-right supporter on June 16, 2016.
In May 2010, East Ham MP Stephen Timms was stabbed twice in the abdomen by Roshonara Choudhry, an Islamic extremist who claimed she had wanted "to get revenge for the people of Iraq".
Mr Timms suffered serious injuries and according to police was "extremely fortunate not to have been killed". He remains an MP.
Nigel Jones, then MP for Cheltenham, was severely injured in January 2000 when he was attacked in his offices by a man with a sword.
Andrew Pennington, a Gloucestershire county councillor, was killed in the same attack while trying to defend the then-MP.
He was posthumously awarded the George Medal for bravery.
The attacker, Robert Ashman, had been suffering from paranoid schizophrenia and was deemed unfit to stand trial and was ordered to be detained indefinitely in a secure hospital.

"I went into the client's house... came back out and there were loads of armed police, overhead there was an air ambulance as well as a police helicopter. Obviously wondered what the hell was going on, you don't often see armed police around the local area.
"I saw the suspect get put into a police van, get taken away and then they cordoned the whole road and pushed us all down the road.
"What we then heard was that it was David Amess."
He added: "The air ambulance has parked in a field nearby... I assume they're fighting to save his life and then they will take him away in the air ambulance."

"The reality for us is that we see constituents all the time, both in their houses and in surgeries.
"We're out and about, we're always available, we must be available, it's the most critical bit of what makes the British parliamentary system I think one of the most accessible in the world, and that's because we want it that way.
"We don't want to be cowed or frightened into doing something different, and I certainly won't, and I know my colleagues will feel the same.
"So I hope this is resolved very, very quickly, as I say, but we will certainly want to continue the way that we do things.
"Of course there may be some other elements that may be added to it, but notwithstanding that I want my constituents to have full access and I'm sure David would have felt the same."
