President Donald Trump is continuing to court controversy during his trip to Europe.
Trump has frequently angered British politicians.
On Friday, Mrs May and Mr Trump will go to watch a joint counter-terrorism exercise by British and U.S. special forces at a military base. "What is interesting is Trump is not criticising mayors of those cities but he is criticising me", he said in an interview on the BBC Today programme.
Top it off with the introduction of trade policies that have targeted some European industries - even though European nations are longtime friends accustomed to easy trade with the USA - and it is not surprising that Trump's itinerary will keep him out of central London on Friday, when large protests are planned.
At a welcoming garden party, the Beatles track "We can work it out" played in the background. "I think he's got what it takes", he added.
But some 77 per cent of Britons have an unfavourable view of Trump, according to a poll by YouGov with 1,648 respondents.
Writer Owen Jones has also been a fundamental organiser in the protest, urging his more than 735,000 Twitter followers to stand together against the president.
Mr Morgan, the forthright journalist and broadcaster, hit back and questioned why the London mayor had not been so vocal over the visit of controversial Turkish President Recep Erdogan.
A large "Human Rights Nightmare" banner has been unfurled by Amnesty International activists across the river Thames on Vauxhall Bridge to protest against the visit.
It appears the president pulled no punches in the interview, which ranges in topics from British Prime Minister Theresa May's "Brexit" plan to the giant "Trump Baby" balloon that's set to fly in London's sky during his visit.
He is due to meet Theresa May, who is seeking a post-Brexit trade deal - days after he said the United Kingdom was in "turmoil". Some plan to stage an "all-night noise protest" outside the barricades surrounding Winfield House later Thursday, with those attending urged to "bring pots, drums and vuvuzelas".
But influential Conservative backbencher Jacob Rees-Mogg, who opposes Mrs May's plan for post-Brexit trade with the European Union, said many Conservative MPs shared his view.
Mr Trump arrives Thursday afternoon following a North Atlantic Treaty Organisation summit in Brussels and largely avoids the capital's centre and the protesters. Trump has since attended the North Atlantic Treaty Organisation summit in Brussels and plans to meet one-on-one with Russian President Vladimir Putin on July 16.
Russian Federation has strongly denied the charge.
The comments will plunge the transatlantic "special relationship" to new lows, making for extremely awkward talks with May when the two meet at her country retreat of Chequers later on Friday.
Protests took place outside the Blenheim grounds in Woodstock, Oxfordshire, with several hundred demonstrators waving banners and placards reading Dump Trump, Not Welcome Here, Protect Children Not Trump and Keep Your Tiny Hands Off My Pussy!
He stressed it was not for him to say, despite owning "a lot of property there" and the fact his mother was born in Scotland.
The Glasgow protest is one of several being held across the country over the next two days, with anti-Trump campaigners also expected to target his Turnberry and Menie golf courses as well as the United States consulate in Edinburgh.
