Thousands began protesting in London as British Prime Minister Theresa May welcomed US President Donald Trump to her official country residence for a meeting that is expected to be unusually tense, after he trashed her Brexit plan in a newspaper interview.
Trump walked ahead of the queen while inspecting troops from the Coldstream Guard and did not bow when he met her - a couple of minor protocol breaches - but the meeting went smoothly.
Trump replied: "I think I could have". I haven't been there in a long time.
He told the tabloid that's part of why he's spending so little time in the city, saying: "I guess when they put out blimps to make me feel unwelcome, no reason for me to go to London".
Just hours before Trump's interview was published, May invoked Winston Churchill, a hero of Trump, as she addressed the U.S. president and business leaders at a black-tie dinner at Blenheim Palace, the grand 18th-century country house that was the birthplace of the British World War Two leader.

And just in case you're wondering, this is the same castle where Prince Harry and Meghan Markle's wedding festivities took place back in May. "He has done a bad job". Look at what is going on in London, ' Trump said.
Trump said it made him feel "unwelcome".
"The idea that we restrict freedom of speech, the right to assemble, the right to protest because somebody might be offended is a slippery slope", he told BBC radio, adding that a protest to welcome Trump was also planned.
More than 10,000 people signed a petition calling on the mayor to "let Trump Baby fly", a six-meter balloon depicting Mr Trump as a nappy-clad orange baby.
Although Trump was apparently happy to meet with the matriarch, many in the United Kingdom were not.
