Climate activists gathered to mark the end of protests that caused 11 days of disruption across London.
More than 1,100 people have been arrested since campaigners from Extinction Rebellion first blocked traffic in the capital on 15 April.
On the final day of action, protesters blocked roads, climbed on a train and glued themselves together in London’s financial district.
Hundreds of people met in Hyde Park for a “closing ceremony”.
Campaigners sat on the grass next to Speaker’s Corner – widely considered London’s home of free speech – singing and listening to musicians.
Transport for London said all roads are open around Marble Arch.
Skeena Rathor, of Extinction Rebellion, welcomed the “rebels” to the ceremony and described the crowd as “beautiful beings”, adding: “This is our pause ceremony.
“Welcome to the beginning of our pause.”
She invited the crowd to “begin a process of reflection”, adding: “Thank you for what you have done this week. It is enormous. It is beyond words.”
The crowd cheered and clapped when a speaker said “the police were amazing” during the days of blockades.
“We will leave the physical locations but a space for truth-telling has been opened up in the world,” event organisers said on their Facebook page.
“We would like to thank Londoners for opening their hearts and demonstrating their willingness to act on that truth.
“We know we have disrupted your lives. We do not do this lightly. We only do this because this is an emergency.”
Extinction Rebellion is urging the government to “tell the truth” about the scale of the climate crisis. It wants the UK to reduce carbon emissions to net zero by 2025 and a Citizens’ Assembly set up to oversee the changes needed to achieve this.
On Thursday, 26 people were arrested on suspicion of aggravated trespass outside the Stock Exchange and on Fleet Street, bringing the total number of arrests up to 1,130 since the protests began on 15 April, the Met Police said.
Four people stood on top of a Docklands Light Railway (DLR) train while another glued herself to a train.
Five people were arrested on suspicion of obstructing the railway, the British Transport Police said.
Meanwhile, Dame Emma Thompson, who joined the activists on Saturday, has defended flying from Los Angeles to London to take part.
The actress said it was “very difficult to do my job without occasionally flying” but she was “in the very fortunate position of being able to offset my carbon footprint”.
More than 10,000 police officers have been deployed during the action.
Mayor of London Sadiq Khan said the protests had been a “huge challenge for our over-stretched and under-resourced Metropolitan Police”.
The Met said on Wednesday it had imposed new conditions under the Public Order Act on the protest area in Marble Arch, making it a criminal offence to protest outside a designated area or incite others to protest outside of it.
The conditions will remain in force until Saturday.
US President Donald Trump will make a state visit to the UK in early June, Buckingham Palace is expected to announce later.
The president was promised the visit by Prime Minister Theresa May after he was elected in 2016 – but no date was set.
Downing Street did not comment on the matter when contacted by the BBC.
President Trump and the First Lady, Melania, met the Queen at Windsor Castle when they came to the UK in July 2018 for a two-day working visit.
During the trip, the president also held talks with met Mrs May at Chequers before heading to Scotland, where he owns the Turnberry golf course.
The president’s last visit was marked by demonstrations around the UK.
In London, thousands of people took to the streets to voice their concerns.
And in Scotland, people showed their displeasure, both in Edinburgh and at Turnberry.
The National Police Chiefs’ Council estimated that the police operation for the president’s 2018 visit cost nearly £18m.
It said 10,000 officers from across the country were needed to cover the occasion.
The campaigners behind the 2018 protests – the Stop Trump coalition and Stand Up To Trump – have vowed to mobilise “huge numbers” once again in response to the visit.
Commons Speaker John Bercow has previously said he would be “strongly opposed” to Mr Trump addressing the Houses of Parliament during a state visit.
A spokeswoman for the Speaker’s Office said a request to address Parliament would be “considered in the usual way”, but did not say whether a request had yet been received.
What is a state visit?
A state visit is a formal visit by a head of state and is normally at the invitation of the Queen, who acts on advice from the government.
State visits are grand occasions, but they are not just ceremonial affairs. They have political purpose and are used by the government of the day to further what it sees as Britain’s national interests.
Once the location and dates are confirmed, the government, the visiting government and the royal household will agree on a detailed schedule.
So what is involved?
The Queen acts as the official host for the duration of the trip, and visitors usually stay at either Buckingham Palace or Windsor Castle.
There is usually a state banquet, and a visit to – and speeches at – the Houses of Parliament may be included. The Speaker of the House of Commons is one of three “key holders” to Westminster Hall, and as such, effectively holds a veto over who addresses Parliament.
The Queen usually receives one or two heads of state a year. She has hosted 109 state visits since becoming monarch in 1952.
The official website of the Queen and the Royal Family has a full list of all state visits since then, including details of how the ceremonies unfold.
Harlequins lock Stan South will leave the Premiership club at the end of the season and join Championship side Coventry on a two-year contract.
The 22-year-old has made 11 appearances this term and played for 40 minutes in Quins’ European Challenge Cup semi-final defeat by Clermont on Saturday.
South has also represented England at under-18 and under-20 level.
“We want to thank Stan for everything he has given the club,” Harlequins head of rugby Paul Gustard said.
London’s top transport boss should consider quitting, a report into Crossrail’s delays has recommended.
The project, to build a new railway underneath central London, was due to open in December 2018 but it might not open until 2020 at the earliest.
A report by the London Assembly has recommended Transport for London (TfL) commissioner Mike Brown reflect “on whether he is fit to fulfil his role”.
TfL said the project’s delay was down to the previous Crossrail management.
A spokesperson for London Mayor Sadiq Khan, who is responsible for the transport authority, said the mayor had “every confidence” in TfL’s commissioner.
Mr Brown has not yet commented but a spokesperson for TfL said the commissioner had kept the mayor informed of all of the project’s developments.
Construction work for the project began in May 2009, with tunnelling commencing in May 2012.
However, the scheme has come under increasing pressure as its costs have increased.
Three emergency cash injections have seen the cost of the route rise from £14.8bn to £17.6bn, with the first rise revealed in July 2018.
The report claims warnings the project would not open on time were downplayed by Mr Brown.
It also concluded better scrutiny was needed of the governance of the project as well as assurances people with the correct skills needed were in place.
A corporate culture of transparency should be instilled and the “overly optimistic corporate culture” needed to be kept in check by independent reviewers.
It added future infrastructure projects should strive to keep designs simple rather than include bespoke features in order to reduce risks to the budget and timelines.
Chair of the Assembly’s transport committee, Caroline Pidgeon, said: “It is frustrating that top Crossrail executives have not taken responsibility for their mismanagement of the project in its later stages.
“This despite the fact that they were taking home eye-watering salaries and bonuses to deliver the project.”
What is Crossrail?
Crossrail is a new railway that will run beneath London from Reading and Heathrow in the west through central tunnels across to Shenfield and Abbey Wood in the east.
Construction began in 2009 and it is Europe’s biggest infrastructure project – it had been due to open in December 2018 although last summer that was pushed back to autumn 2019.
It has been officially named the Elizabeth Line in honour of the Queen and will serve 41 stations.
An estimated 200 million passengers will use the new underground line annually, increasing central London rail capacity by 10% – the largest increase since World War Two.
Crossrail says the new line will connect Paddington to Canary Wharf in 17 minutes.
