The Parliament has debated banning him. The prime minister has called his comments “stupid” and promised that the country would unite against him. Scotland Yard has said he “could not be more wrong.” But despite the unmitigated hostility toward him in Britain, Donald Trump will be visiting the country later this month in his first trip abroad since becoming the presumptive Republican presidential nominee.

The visit will come June 24, and will ostensibly be about business, not politics. He’s scheduled to attend the official opening of one of his Scottish golf courses that day, according to a statement issued by the Turnberry resort Wednesday.

“Very exciting that one of the great resorts of the world, Turnberry, will be opening today after a massive 200 million (British pound) investment,” Trump was quoted as saying in a press release issued by the resort. “I own it and I am very proud of it. I look forward to attending the official opening of this great development on June 24th.”

But business aside, the visit is likely to cause awkward politics for his British hosts. The visit could not come at a more sensitive moment for Britain. The country will be voting on June 23 in a referendum on whether to stay in the European Union. The result may not be known until the following morning, when Trump is set to fly in.

Trump has publicly backed the idea of a British exit – popularly known as Brexit.

His stance puts him sharply at odds with nearly every major world leader, except Russian President Vladimir Putin, who has not taken a side. President Obama and Britain’s European allies have come out strongly for Britain staying in the European Union.

So has British Prime Minister David Cameron, who may be staking his premiership on the vote.

It is not clear whether Trump will visit London during his trip. Nor is it clear whether Cameron will meet the Republican candidate.

Cameron was vague when asked about the possibility late last month.

“Candidates do often come through London,” he said in reply to a question at a meeting of the Group of 7. “I’ve met them before. But we have no firm dates in the diary.”

A spokesman for the Scottish government said Nicola Sturgeon, the first minister of Scotland, has “no plans to meet Trump.”

The Republican candidate has been chastised by British politicians from across the political spectrum, and he has few if, any prominent, backers in the country.

After Trump proposed banning Muslims from entering the United States late last year, Cameron, a Conservative, took to the floor of the House of Commons to call Trump’s remarks “divisive, stupid and wrong.” He also said that a Trump visit to the United Kingdom would “unite us all against him.”

Asked about the comments, Trump told ITV News that he and Cameron were “not going to have a very good relationship.”

Also last year, a Trump suggestion that London was filled with no-go areas because of the activities of Islamic extremists earned an unusual rebuke from London’s Scotland Yard, also known as the Metropolitan Police.

“We would not normally dignify such comments with a response, however on this occasion we think it’s important to state to Londoners that Mr. Trump could not be more wrong,” a spokeswoman for the police said in a statement.

She offered Trump a tutorial: “Any candidate for the presidential election in the United States of America is welcome to receive a briefing from the Met Police on the reality of policing London.”

In January, Parliament held an hours-long debate on whether to ban Trump from entering Britain under laws that allow the prohibition of those who promote hate speech. It was a first for a country that has long prided itself on being Washington’s closest ally. British politicians are normally loath to interfere in American politics, but they made an exception for Trump.

Over three hours, parliamentarians took turns jabbing him with a range of insults. No one rose to defend him. But members ultimately opted not to recommend a ban, reasoning that it was better to prove him wrong – with some even offering to show him around their constituencies if he came for a visit.

There was no word Wednesday on whether those offers still stood.

But some Britons on Wednesday were clearly struggling with the idea that Trump will be on their soil as the presumptive Republican nominee at such a critical moment for the nation.

“Had a nightmare we’d voted for #Brexit, and suddenly Trump was there, it was awful,” one tweeted. “Good thing that’d never happen.”
