Mr Khan was about to start speaking to the Fabian Society in London when he was disrupted by protesters from a organisation called the White Pendragons, who shouted pro-Trump and pro-Brexit slogans.
In a twitter on Friday, Mr Khan pronounced Mr Trump had got the summary that he was “not welcome” in London after the President cancelled a designed revisit to open the new US embassy.
In a video posted on social media, one protester could be listened saying: “Ladies and gentlemen, we’re here currently to make a non-violent, pacific citizen’s arrest.”

As confidence began to appear, those in the assembly started to bother and slow-hand-clap.
But a demonstrator, unruffled by the reception, said: “We mount under Common Law jurisdiction.
“If you hold us, you’ll be finished for common assault. Please mount back, do not hold us.
“We’re not leaving, we’ve paid for a ticket.”
He also accused the Fabian Society of “subverting” the constitution.
The Mayor sat down and flicked by a journal while police escorted the demonstrators away.
Sky News Political Correspondent, Laura Bundock, pronounced the protesters had been sitting “right at the front of the room”, and had behind the start of Mr Khan’s debate for 15 minutes.
The organisation 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 profitable £35 to get in, they were “heading to the pub afterwards”.

Mr Khan has called President Trump’s policies “divisive”, describing them as the “polar opposite” of London’s values of “inclusion, farrago and tolerance”.
When Mr Khan resumed his debate he done light of the disruption, saying: “On the and side we wasn’t served with a P45,” referring to Theresa May’s Tory discussion speech, interrupted by a prankster.
He added: “It is a pleasure to be here even yet we were dreaming by the actions of what some would call very fast geniuses.”
Mr Trump recently used the difference ‘stable’ and ‘genius’ to report himself.
