The NATO summit will be held in London next week and British Prime Minister Boris Johnson has a message for President Trump ahead of his attendance:

Butt out of UK elections.

Trump drew global criticism in October after he criticized Labour Party leader Jeremy Corbyn, saying he would be “so bad” for Britain.

Reuters reports that the Trump administration has already signaled they have no intention of getting involved in UK election politics during the visit.

On Friday, a senior Trump administration official told reporters that Trump is “absolutely cognizant of not, again, wading into other country’s elections.”

But senior Conservatives are nervous that Trump could upset the campaign when in London, just over a week before the Dec. 12 election, which polls indicate Johnson is on course to win.

“What we don’t do traditionally as loving allies and friends, what we don’t do traditionally, is get involved in each other’s election campaigns,” Johnson, 55, told LBC radio.

“The best (thing) when you have close friends and allies like the U.S. and the UK is for neither side to get involved in each other’s election.”
