The agenda for Trump and May on Friday includes discussion on relations with Russian Federation, ahead of a summit in Finland on Monday between Trump and President Vladimir Putin.
But 51% again say that the United States president is untrustworthy to negotiate a trade deal with, including 38% who say he is "very untrustworthy".
"I want Trump to come out and say unequivocally "Russia meddled in our election" and I want him to press Putin on that", Jankowicz said. It was one of more than a hundred protests police expected during Trump's four-day trip.
Relations had never been more special, he said, and any criticism was "fake news".
"I think he has done a bad job on crime, if you look, all of the terrible things going on there, with all of the crime that is being brought in", Trump said, later adding that he thinks Khan has insulted him by not being "hospitable to a government that is very important". He was decidedly critical of May and her Brexit plan, saying he "would have done it much differently". "I was very surprised and saddened that he was getting out of government". "I think they like me in the UK".
He used the forum to again blast the "rigged witch hunt", his term for Special Counsel Robert Mueller's investigation into Russian meddling and potential collusion with Trump campaign associates in the 2016 presidential election, saying it "hurts" USA and Russian relations.
He said the US "pays tens of Billions of Dollars too much to subsidize Europe" and demanded that members meet their pledge to spend 2 percent of GDP on defence, which "must ultimately go to 4%!"
Mr Trump is due to face a press conference later in the day.
'I think he is a great representative for your country.
Trump blazed into the summit yesterday by demanding that allies reach their commitment to increase spending to two per cent of GDP "immediately" - instead of by 2024 as previously agreed.
Dawn Butler, an lawmaker from the opposition Labour Party with responsibility for women and equalities, told TIME: "Theresa May has failed to be a critical friend to Trump". He's representing Russian Federation. I'm representing the United States. "And I know that's valued very highly over here and people can disagree strongly and still go out to dinner".
Trump also spoke on immigration policy in the interview, saying that Europe was losing its identity and culture because of an influx of migrants.
Trump said he did not criticize May during the interview and said the British tabloid did not include all the good things he said about her.
"If you think of it, for so many years she's represented her country, she's never really made a mistake", he said.
'I actually told Theresa May how to do it but she didn't agree, she didn't listen to me.
Trump, as he has before, criticized London's mayor, Sadiq Khan, as having "done a very bad job on terrorism".
"We have this stupidity going on, pure stupidity, but it makes it very hard to do something with Russia because, anything you do, it's like: "Russia, oh he loves Russia", Trump said.
At the centre of the demonstration is the giant six-metre-high balloon, which was cleared by the London mayor's office to fly over the centre of the city.
