US President Donald Trump has apologised for the first time for retweeting a British far-right group's videos apparently showing Islamist violence, in an ITV interview aired in Britain on Friday.
"If you're telling me they're horrible racist people, I would certainly apologise if you'd like me to do that," he told Good Morning Britain's Piers Morgan during the interview, conducted in Davos on Thursday.
Trump sparked outrage in Britain in November when he retweeted, in quick succession, three anti-Muslim videos posted by Jayda Fransen, the deputy leader of Britain First who was in 2016 convicted of religiously aggravated harassment of a Muslim woman.
Morgan accused the president of causing "huge anxiety and anger in my country, because Britain First is basically a bunch of racists, fascists".
"Of course I didnt know that," Trump responded in excerpts of the interview aired on Friday.
"I know nothing about them (Britain First), I know nothing about them today, other than I read a little bit," he added.
"Certainly I wasn't endorsing anybody. Perhaps it was a big story in the UK, but in the United States it wasn't a big story. I am the least racist person that anybody is going to meet.
"When you do those retweets they can cause problems because you never know who's doing it to start off with," the president told Morgan.
Trump was less apologetic about tweeting the content of the unverified videos.
'I love Britain'
The incident caused a huge headache for British Prime Minister Theresa May, who said that Trump was "wrong" to send out the tweets.
However, the two leaders met in Davos on Thursday, and Trump was keen to downplay talk of a rift, with Britain desperate for a trade deal with the US as it leaves the European Union.
"The real me is someone who loves Britain, loves the UK, I love Scotland; very special people and a very special place," he said.
"I don't want to cause any difficulty for your country."
Turning to May, Trump insisted: "We actually have a very good relationship although a lot of people think we don't.
"I support her, I support a lot of what she does and I support you militarily very much. We will come to your defence should anything happen," he told the breakfast news show.
Trump was due to make a state visit to Britain this year, but recently pulled out of a ceremony to open the new US embassy in London following the spats, and after it appeared the visit would be met with protests.
Trump said "I don't care" about the potential protesters, adding: "I think a lot of the people in your country like what I stand for, I do stand for tough borders."
May spoke to the World Economic Forum in Davos on Thursday, with Trump set to deliver his address later on Friday.
