Trump used Twitter to retweet videos of from the far right group which appears to show Muslims committing crimes.

US leader has criticised Mrs May saying: “Theresa May, don’t focus on me, focus on the destructive Radical Islamic Terrorism that is taking place within the United Kingdom. We are doing just fine!”

Downing Street previously released a statement condemning the tweets saying “it is wrong for the President to have done this”.

Trump retweeted three posts by Britain First’s Deputy Leader Jayda Fransen to his 43.6million followers.

The posts included unverified videos titled "Muslim Destroys a Statue of Virgin Mary!" and "Muslim migrant beats up Dutch boy on crutches!"

His actions faced widespread criticism from UK politicians who were furious that he appeared to endorse the group’s political beliefs.

Cabinet minister Sajid Javid, who was brought up in a Muslim family, used Twitter himself to criticise the President’s apparent support for the radical right group.

He said: “So POTUS has endorsed the views of a vile, hate-filled racist organisation that hates me and people like me. He is wrong and I refuse to let it go and say nothing.”

And Mayor for London Sadiq Khan said: “Britain First is a vile, hate-fuelled organisation whose views should be condemned, not amplified.”

The actions from the UK’s “special” ally have led to questions as to whether a US state visit, promised to Trump when Theresa May visited Washington DC earlier this year, should still take place.

However, Downing Street earlier said that the visit would go ahead as planned.

In a statement, they said: “Britain First seeks to divided communities through their use of hateful narratives which peddle lies and stoke tensions. They cause anxiety to law-abiding people.

“British people overwhelmingly reject the prejudiced rhetoric of the far-right, which is the antithesis of the values which this country represents: decency, tolerance, and respect.”

The Government is yet to officially respond to Trump’s criticisms of Theresa May.

However, Carrie Symonds, the Director of Communications for the Conservatives, has used her personal Twitter account to give her view.

She tweeted: “Wrong twitter handle. And that's just the start.”

Her response referred to the fact Trump had to send his tweet twice after he accidentally directed his first tweet at the wrong person, directing his anger at a woman called Theresa Scrivener, who only has six followers.

White House press secretary Sarah Sanders told reporters yesterday she would not comment on the veracity of the videos.

In footage shared by broadcaster NBC News, she said: "I'm not talking about the nature of the video. I think you're focusing on the wrong thing.

"The threat is real and that's what the president is talking about: the need for national security, the need for military spending, and those are very real things, there's nothing fake about that.

"The threat is real, the threat needs to be addressed, the threat has to be talked about and that's what the president is doing in bringing that up."
