The US president is due to fly straight from the summit to Stansted airport for the four day visit, which will include a black tie dinner at Blenheim Palace, talks with May at Chequers and afternoon tea with the Queen. Thousands of protesters were expected to gather outside the luxurious residence later Thursday.
Trump will then spend a private weekend in Scotland with his wife, where he owns two golf resorts.
Unlike visits from previous presidents, he won't be spending much time in London after his arrival.
"I think they like me in the UK".
But there are still plenty of detractors, as loudly demonstrated by a passenger in auto driving past the United States flag-adorned pub who shouted "F*** Trump", to which Mr Smyth chuckled. "It seems so un-American". We greatly respect America as a generous place built up by immigrants over the years.
"Boris Johnson's a friend of mine, he's been very nice to me, very supportive and maybe I'll speak to him when I get over there".
This morning, Mr Trump dropped a hand grenade into the Prime Minister's carefully crafted proposal by saying "I don't know if that's what they voted for".
The organisers behind the blimp however, said they were just "poking fun" and "hope Trump sees it".
Mr Smyth, who is originally from Ireland, said Trump fans had been given a bad rap, and there had been lots of support for the pub's temporary renaming. Both those accords were the result of years of painstaking diplomacy by European leaders, and Trump unilaterally trashed them.
In the Tuesday memo, the U.S. Embassy in London alerted citizens to the "numerous demonstrations" that could "attract large crowds" that may be less than agreeable toward Americans.
Trump has been quick to criticize British society, telling a National Rifle Association convention in May that the British didn't have guns but had so much knife crime that one hospital was like a military war zone with its floors awash with blood, a false statement quickly rebutted by British physicians and politicians.
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.
