Donald Trump's advisers fear he may not be able to stop himself intervening in the UK election when he visits London for a Nato summit this week, despite a plea from British Prime Minister Boris Johnson.
The US president has been told Johnson does not want him to offer his support publicly, amid fears an endorsement could end up harming the Prime Minister's chances, and improving those of Labour leader Jeremy Corbyn.
But an insider told the Sunday Telegraph Trump may ignore the advice because he finds it hard to understand why his support would not be welcome.
"He's got the advice — but he doesn't have to take it," a person close to the president said.
