Meghan Markle's nephew is reported to have attempted to take a knife into a nightclub near Windsor Castle because he was worried by Donald Trump's saying London was "like a warzone".

Tyler Dooley, the 25-year-old son of the Duchess of Sussex's brother, Thomas Markle, was not invited to the wedding, but travelled to London with the intention of appearing as a pundit on television.

On Saturday night, according to reports in The Sun, he went to the Bacchus nightclub in Kingston with his mother Tracy - Mr Markle's ex-wife - and his older brother TJ, 26.

As their party was searched entering the club, Mr Dooley, a cannabis farmer from Oregon, realised the four-inch blade would be discovered, and told bouncers on the door that he had a knife.

He told another partygoer, according to The Sun: “I just brought it because Donald Trump said London was like a war-zone. I had it for protection.”
