Four Extinction Rebellion protesters glued themselves to a fence outside Jeremy Corbyn's home in Islington.
It came as the climate change activists continued their week of 'International Rebellion' which has seen them shut down Waterloo Bridge and Oxford Circus and glue themselves to a train at Canary Wharf.
The four activists, who glued themselves to the Labour leader's fence and have been spoken to by police, said it was a bid to get the Labour leader to commit to tackling climate change.
They said they are "all Jeremy Corbyn supporters" but want the Labour Party to go further than declaring a "climate emergency".
Mr Corbyn declined to meet the protesters, a spokesman told reporters waiting outside.
The activists had brought gifts of Easter eggs and flowers for the Labour leader and left them outside his home when they arrived at about 3pm. But they were returned to the group by Mr Corbyn's wife Laura Alvarez who was upset by their presence.
The Labour leader then left his home.The group abandoned their protest shortly before 5pm.
When asked why, Tracee Williams, 55, said: "I don't think this was a misstep but whether we'd do it again, I'm not so sure.
"We just really felt we had to bring it to his front door.
"I feel absolutely terrible about upsetting his wife."
Earlier, Skeena Rathor, a Labour district councillor for Stroud said: "I feel really sorry and sad and guilty."
They said they have had conversations with Mr Corbyn's staff about a potential meeting next week.
Earlier, climate protesters from Extinction Rebellion glued themselves to a train at a station in London as a third day of protests got under way. The protests have cost London businesses more than £12 million.
The protesters, a man and a woman, climbed on top of a Docklands Light Railway train and said they were staging a “peaceful protest."
Another man glued himself to the train's window. He was prised off the window by police as he was arrested.
Speaking at Oxford Circus, where protesters are camped out in the middle of the busy crossroads, environmental campaigner and TV presenter Chris Packham justified the disruption to the transport network.
Mr Packham said commuters annoyed by travel disruptions during the protest should know that the activists were demonstrating because of their concerns for tomorrow.
He added: "People have to realise if their life is being disrupted today the reason is we have grave concerns for tomorrow."
He said demonstrators were not picking a fight with the police, and added: "The relationship with the police has been good - I know there have been arrests, but they have been good-natured.
"The police are doing their job. We are not here to fall out with the police but we are here to draw attention to our Government - and the world's governments - of the pressing concerns."
It emerged today that shops and businesses in the West End have lost more than £12 million due to the protests.
The sum was revealed by the New West End Company as activists threatened to escalate the demonstration with action to disrupt commuters on the Tube and trains.
Extinction Rebellion (XR) have been bringing transport systems in London to a standstill in a move it called “the Pause”, an attempt to get people to stop and think about climate change.
British Transport Police have deployed an extra 150 officers on patrols on Tube and rail stations to head off disruption with officers prepared for action, including protesters getting on tracks.
Wi-fi was switched off across the Tube network this morning in an effort to prevent protesters from co-ordinating activities and sharing videos on social media.
Superintendent Matt Allingham, of BTP, said: “We will not tolerate any activity which disrupts the millions of passengers who rely on using the rail network in London.”
By midday on Wednesday, police had arrested a total of 300 protesters.
Sefan White, 24, who works for a company that produces bar snacks, was stopped from getting to work by them.
He said: "I'm devastated. I'm trying to get to a job now. We've got to go round Camden on a 30-pub journey and we're going to be late now. We're probably going to lose money today.
"They've had their picture, fair enough, that's all you need now. Why is he spending 15 minutes on top of the tube? Explain that."
On Wednesday morning Extinction Rebellion said it would disrupt one London Overground line at 11am.
A statement said: "Our aim is to create moments in time when humanity stops and fully considers the extent of the harm we have done and are doing to life on earth.
"It is vitally important at this time. It is a matter of life and death - whether you live in Tower Hamlets or Taipei, Melbourne or Mumbai."
Wi-Fi at stations has been disabled in a bid to stop activists intent on disrupting services co-ordinating protests.
A British Transport Police (BTP) spokeswoman said: "In the interests of safety and to prevent and deter serious disruption to the London Underground network, BTP has taken the decision to restrict passenger Wi-Fi connectivity at Tube stations.
"We apologise for any inconvenience this may cause and we would like to assure passengers that this decision is not taken lightly and will be reviewed throughout the day."
On the protest in Canary Wharf, she added: "At 10.50am officers were called to Canary Wharf DLR station after reports of protesters obstructing a DLR train in the station platforms.
"Units are in the process of responding, including specialist teams trained in protest removal."
London Mayor Sadiq Khan said that while he shared the passion of the protesters about the urgent need to tackle climate change, he was "extremely concerned" about plans to disrupt the London Underground.
In a statement posted on Twitter he said: "It is absolutely crucial to get more people using public transport, as well as walking and cycling, if we are to tackle this climate emergency - and millions of Londoners depend on the Underground network to get about their daily lives in our city.
"Targeting public transport in this way would only damage the cause of all of us who want to tackle climate change, as well as risking Londoners' safety and I'd implore anyone considering doing so to think again."
XR demonstrations have been taking place at Parliament Square, Waterloo Bridge, Oxford Circus and Marble Arch this week.
The protests have led to road closures, traffic gridlock and serious disruption to public transport and local businesses, with 55 bus routes closed and 500,000 people affected.
Groups of protesters remained in place through the night and into Wednesday at several locations, blocking the road at Marble Arch and Oxford Circus.
A woman at Marble Arch, who gave her name as Virginia, said she had come from Oxford to join the protest "to keep the planet in good nick for my grandchildren".
Scotland Yard said on Wednesday that "contingency plans are in place should custody suites become full".
