A number of posts are being shared on social media with the hashtag #ShowYourRumpToTrump, in the wake of Mr Trump's controversial comments on the recent London Bridge terror attack.

"Pathetic excuse by London Mayor Sadiq Khan who had to think fast on his 'no reason to be alarmed' statement. MSM is working hard to sell it!" Mr Trump tweeted in the aftermath of the attack.

He'd previously used the attack to justify his proposed "travel ban" on Muslims.

Mr Khan has since called for Mr Trump's visit to be cancelled.

"I don't think we should roll out the red carpet to the president of the USA in the circumstances where his policies go against everything we stand for," he told Channel 4 News.
