The girlfriend of a victim of the London Bridge terror attack has broken down in tears at a vigil in his memory.
Leanne O’Brien wept and clutched a cuddly toy while supported by family and friends at the event outside the Guildhall in Cambridge on Monday.
Her boyfriend, Jack Merritt, 25, and fellow former University of Cambridge graduate Saskia Jones, 23, died after being stabbed by convicted terrorist Usman Khan, 28, during a prisoner rehabilitation event in London on Friday.
Meanwhile, prime minister Boris Johnson and opposition leader Jeremy Corbyn paid their respects at a separate event in London’s Guildhall Yard, observing a minute's silence alongside members of the public.
Mayor of London Sadiq Khan told those gathered in the capital: "We come together this morning as Londoners to remember, to honour and to mourn the innocent lives lost as a result of this horrific terrorist attack on Friday.
"The best way to defeat this hatred is not by turning on one another but by focusing on the values that bind us."
The Queen has been among those to praise the brave actions of members of the public who tackled the terrorist on Friday.
Usman Khan, 28, was on licence and wearing an electronic monitoring tag when he launched the attack, which injured three others, after he was invited to a prisoner rehabilitation conference at Fishmongers’ Hall on Friday afternoon.
The event was held by Learning Together, a programme associated with Cambridge University's Institute of Criminology.
It was reported that Khan had been a case study for the group and that he wrote a poem and thank-you note to the initiative for supporting him.
Khan had previously written that he wanted to be deradicalised and become a “good British citizen”.
The attack has prompted the Ministry of Justice to review the licence conditions of every convicted terrorist released from prison, which Boris Johnson said was "probably about 74" people.
The prime minister has vowed to take steps to ensure people are not released early when they commit serious offences.
But the family of Mr Merritt, from Cottenham, Cambridgeshire, asked for his death to not to be used to justify introducing "even more draconian sentences" on offenders, in a heartfelt tribute released on Sunday.
They said: "He lit up our lives and the lives of his many friends and colleagues, and we will miss him terribly.
"Jack lived his principles; he believed in redemption and rehabilitation, not revenge, and he always took the side of the underdog.
"We know Jack would not want this terrible, isolated incident to be used as a pretext by the government for introducing even more draconian sentences on prisoners, or for detaining people in prison for longer than necessary."
And in a tweet on Sunday evening, Mr Merritt's father David said: "Don't use my son's death, and his and his colleague's photos – to promote your vile propaganda.
"Jack stood against everything you stand for – hatred, division, ignorance."
Ms Jones, a volunteer with Learning Together from Stratford-upon-Avon, Warwickshire, was described as having a "great passion" for providing support to victims of crime by her family.
In a statement, they said: "She was intent on living life to the full and had a wonderful thirst for knowledge, enabling her to be the best she could be.
"Saskia had a great passion for providing invaluable support to victims of criminal injustice, which led her to the point of recently applying for the police graduate recruitment programme, wishing to specialise in victim support."
Khan, who was living in Stafford, had been given permission to travel into the heart of London by police and the probation service.
Convicted of terror offences in February 2012, he was released from prison on licence in December 2018, halfway through his 16-year prison sentence.
He launched the fatal attack at the Learning Together event just before 2pm on Friday.
Armed with two knives and wearing a fake suicide vest, he was tackled by members of the public, including ex-offenders from the conference, among them a murderer on day release, before he was shot dead by police.
