It comes after Sadiq Khan said Donald Trump had realized he is “not welcome” in London after cancelling a planned visit.
Supporters of US President Donald Trump have disrupted a speech by Sadiq Khan, calling for the London Mayor to be arrested.
Mr Khan was about to start speaking to the Fabian Society in London when he was disrupted by protesters from a group called the White Pendragons, who shouted pro-Trump and pro-Brexit slogans.
It came after a tweet by Mr Khan on Friday, in which he said Mr Trump had “got the message” that he was “not welcome” in London after the President cancelled a planned visit to open the new US embassy.
In a video posted on social media, one protester could be heard saying: “Ladies and gentlemen, we’re here today to make a non-violent, peaceful citizen’s arrest.”
As security began to appear, those in the audience started to heckle and slow-handclap.
But a demonstrator, unperturbed by the reception, said: “We stand under common law jurisdiction.
“If you touch us, you’ll be done for common assault. Please stand back, do not touch us.
“We’re not leaving, we’ve paid for a ticket.”
The demonstrator also accused the Fabian Society of “subverting” the constitution.
Mr Khan sat down and flicked through a newspaper while police escorted the demonstrators away.
Sky News political correspondent Laura Bundock said the protesters had been sitting “right at the front of the room”, and delayed the start of Mr Khan’s speech for 15 minutes.
The group told her that MPs had “broken their oaths of office”, adding that they were “employed by us, the people” and “should do as we say”.
After paying £35 to get in, they said they were “heading to the pub afterwards”.
