Nigel Farage has arrived at Trump Towers amid rumours he will be the first British politician to meet the President-elect since his election.
The interim UKIP leader’s camp has refused to comment on whether the two will meet – but if he does it is likely to irk Downing Street.
Earlier, Mr Farage told American TV that Theresa May had to “mend fences” when she finally met Mr Trump.
He claimed the Prime Minister’s team had been “quite rude” about the President-elect.
His own visit to New York comes as thousands again hit the streets across America in protest to the Republican’s victory – including a 2,000-strong brigade heading towards Mr Trump’s Manhattan landmark.
On Friday night a Trump protester was shot after a confrontation in Portland, Oregon. His injuries were not life threatening.
While the protests continue for a fourth day Stateside, Mr Farage believes the UK could benefit from Mr Trump taking the White House as the billionaire is “an Anglophile”.
“He understands and recognises what our two great nations have done together between us. And thank goodness we’re coming to the end of an American president who loathed us,” Mr Farage told Fox News.
Wearing a badge showing US and UK flags, Mr Farage told Fox the two countries should follow the example of Ronald Reagan and Margaret Thatcher.
He said they had shrugged off criticism and their policies “made the world a better place”.
But he cautioned that getting back to the famous relationship of the 1980s would need careful diplomacy when the Prime Minister gets to meet Mr Trump.
“Mrs May’s team have been quite rude about Trump so there are some fences to be mended,” said Mr Farage.
However, he said it would not be right for the President-elect to snub Mrs May.
“I think he’s got to meet her … We can have a sensible trade relationship, cut tariffs, we’re massive investors in each other’s countries. There’s a bright future.”
Earlier this week Mr Farage told a radio show that Mr Trump should “schmooze” Mrs May but “don’t touch her for goodness sake”.
During the election campaign Mr Farage shared a stage with the President-elect and addressed his supporters.
The billionaire regularly referred to Brexit as source of inspiration and said Mr Farage had “done an amazing thing”.
The UKIP figurehead never explicitly endorsed Mr Trump but commented that he “wouldn’t vote for Hillary Clinton if you paid me”.
He has said he would like to be Mr Trump’s special adviser to Europe, but acknowledged: “It’s probably not going to happen.”
His latest comments come as Mr Trump appeared to pull back on his election pledge to repeal Obamacare.
