Number 10 wished "good luck" to Donald Trump today despite the presidential candidate suffering a series of allegations of lewd behaviour towards women.

The good wishes were delivered to both Mr Trump and Hilary Clinton at a briefing by Downing Street officials, while Theresa May is away on a trade trip to India.

Asked if the Prime Minister had any message for the candidates, a Downing Street spokesman said: "I think the Prime Minister would wish them both good luck. "

Pressed on whether the PM would back Mr Trump despite the allegations against him, the spokesman said: "It is a matter for the American electorate who wins the American election, not us."

Only this morning Theresa May personally delivered a veiled attack on Mr Trump, saying: "I take a simple view about the way in which I like to see campaigns being conducted.

"I like them to be conducted in a calm and measured way with proper consideration of the issues.

"As for the result of the election, it's up to the American people and we will know that very soon."

Liberal Democrat Leader Tim Farron said: "Donald Trump is not just mad and bad but he’s also dangerous. Why would you wish him luck?
