British MP David Lammy also issued a harsh condemnation of the retweets, saying the president was not welcome in the U.K.

Trump sharing Britain First. Let that sink in. The President of the United States is promoting a fascist, racist, extremist hate group whose leaders have been arrested and convicted. He is no ally or friend of ours. @realDonaldTrump you are not welcome in my country and my city. — David Lammy (@DavidLammy) November 29, 2017

The husband of murdered MP Jo Cox also spoke out, saying Trump "should be ashamed of himself."

Trump has legitimised the far right in his own country, now he’s trying to do it in ours. Spreading hatred has consequences & the President should be ashamed of himself. — Brendan Cox (@MrBrendanCox) November 29, 2017

Cox was murdered by Thomas Mair before the country's Brexit vote in 2016. Mair shouted "Britain first" during the attack.

The deputy leader of the ultranationalist Britain First Party Jayda Fransen disputed that the attack was related to their party.

The Wednesday tweets come after Trump retweeted a series of tweets from Fransen, who is seen as a controversial figure in the U.K.

The BBC reported that Fransen was arrested earlier this month over a speech made in Belfast this summer at a Northern Ireland Against Terrorism rally, while The Guardian reported last year Fransen was found guilty of "religiously aggravated harassment" for verbal abuse of a woman wearing a hijab in front of her four children.

Trump has faced severe backlash for the retweets including condemnation from Piers Morgan and an editor from a frequent Trump-backing outlet, InfoWars.
