"Who would think? But the United Kingdom certainly - they certainly have a lot of things going on".
May had used the Blenheim black tie dinner with political and business leaders to press Trump on the benefits of a free trade deal after Brexit.
May's "business-friendly" Brexit plan - which would keep Britain in a free trade zone for goods with the European Union but mean it has to share some European Union rules - was agreed by her cabinet only last Friday after two years of wrangling since Britons voted to leave the bloc in a 2016 referendum. "We are cracking down right now on the European Union because they have not treated the United States fairly on trading".
He added: "The deal she is striking is a much different deal than the one the people voted on".
Protesters dressed as Donald Trump gather at the gates of Blenheim Palace where US President Donald Trump was attending a evening function with British PM Theresa May. "I think he is a great representative for your country", Trump told The Sun. "I think that's why Brexit happened", he said.
The president also warned that Britain and Europe was "losing its culture" due to mass migration.
"Allowing the immigration to take place in Europe is a shame", he said. "I think he has done a bad job on crime, if you look, all of the disgusting things going on there, with all of the crime that is being brought in".
The convention-shredding president had ignored diplomatic niceties ahead of touching down for the four-day visit - his first to Britain since taking power - by rebuking his beleaguered host as she struggles over Brexit.
"I believe that the people in the UK - Scotland, Ireland, as you know I have property in Ireland, I have property all over - I think that those people they like me a lot and they agree with me on immigration".
They are scheduled to spend Thursday night at the US Ambassador's home Winfield House, which is in Regent's Park. The President's wife Melania will be joining him for the trip, but there is no word on whether Prince Phillip will be joining the festivities. Police worked overtime, their days off cancelled.
Melania wore a pale yellow off-the shoulder gown, with ruched detailing across the bodice creating a corset effect, a full skirt, and a dramatic cape overlay.
The mood was far less jovial in Belgium earlier in the day. All NATO members agreed in 2014 to mandate spending 2 percent of their gross domestic product on defense within 10 years, spending that effectively buys NATO protection. "If they do that, then their trade deal with the US will probably not be made". But there was little evidence other leaders had bowed to his wishes on that front.
Although Trump has said this practice will be stopped, thousands of children remain separated from their parents and face great difficulty locating their relatives. French President Emmanuel Macron quickly disputed Trump's claim that North Atlantic Treaty Organisation allies had agreed to boost defense spending beyond their existing goal of 2 percent of gross domestic product by 2024.
