A blimp depicting President Trump as a nappy-wearing baby was raised in the air in Parliament Square.
Trump acknowledged that he knew about the plan to float a blimp caricature, telling The Sun, "I guess when they put out blimps to make me feel unwelcome, no reason for me to go to London". But when they make you feel unwelcome, why would I stay there?"
His comments are a departure from his remarks earlier in the day when he insisted, "I think they like me a lot in the U.K" although he still insisted even after his Baby blimp lament that real Brits "love the President".
"I actually told Theresa May how to [conduct the Brexit negotiations] but she didn't agree, she didn't listen to me", Trump added.
In that interview, Trump said that May's new, softer approach to Brexit-which would leave Britain sticking to a "common rulebook" with Brussels on goods-would kill off the chances of a highly sought U.S. -U.K. trade deal. "I think that's why Brexit happened".
For her part May, in a Facebook post published before Trump's arrival in the United Kingdom and his Sun interview, insisted that "we are having good discussions with countries we would aim to sign trade deals with, including the U.S., as I will discuss with President Trump when he arrives in the United Kingdom on Thursday". But the president told The Sun that Khan himself had "not been hospitable to a government that is very important".
In other news from this morning's press conference, Trump stunted expectations when he refused to comment on the UK's current Brexit turmoil.
Khan's office gave permission for London protesters to fly a six-metre balloon depicting the USA president as a screaming baby near Parliament as part of nationwide demonstrations against Trump's visit. "This is not the way you behave", Thornberry told broadcaster ITV.
"Allowing the immigration to take place in Europe is a shame", he said.
For no apparent reason, he made a decision to go on the attack against Prime Minister Theresa May, London Mayor Sadiq Khan, and the nation's immigrants - showing that his bigotry crosses borders.
In a newspaper interview on Thursday, Trump revealed the blimp plan had hurt his feelings. "The Chequers agreement reached last week provides the platform for Donald and me to pursue an ambitious deal that works for both countries right across our economies".
"We have enough difficulty with the European Union".
Daniel Jones, a charity communications officer who helped organize the blimp, said the stunt was supposed to make people smile while also underlining serious criticism of the United States leader.
"We will do a trade deal with them and with others around the world", May said.
