Theresa May has doubled down on her criticism of Donald Trump after he retweeted a British far-right group.

Speaking from Jordan, the prime minister said: "Britain First is a hateful organisation. It seeks to spread division and distrust among our communities.

The fact that we work together, does not meant that we're afraid to say when we think that the United States have got it wrong and to be very clear with them, and I'm very clear that retweeting Britain First was the wrong thing to do."

May also confirmed that a state visit was still in place, but a date is yet to be confirmed.

MPs in Britain have called for a stronger rebuke of Trump and for his state visit, which had been expected in 2018, to be cancelled.

A special session in the House of Commons saw politicians accuse Trump of being a "racist" as well as calls for him to delete his Twitter account.

During a press conference as part of her tour of the Middle East, May insisted that despite their disagreement over the tweets, the partnership between the US and the UK remained important.

"This is a long term special relationship, enduring relationship that is there because it is in both our national interest," May said.

On Wednesday, Trump was condemned on both sides of the Atlantic after retweeting graphic and violent videos from the deputy leader of Britain First.

The legitimacy of these videos was later called into question, with all three either being debunked or proven wrong in some form.

Theresa May's spokesperson said on Wednesday evening that Trump was "wrong" to share the hateful messages that Britain First espoused.

But Trump fired back on Twitter, telling Theresa May to focus on the problems in the UK.
