Donald Trump has attacked Sadiq Khan on Twitter once again.
The US president, who misspelled his name as 'Sadique Kahn', said the the Mayor of London was 'incompetent' and 'terrible'.
Without evidence he also said people in London are 'afraid to even walk the streets'.
Mr Khan has been an outspoken critic of the far right President of the United States.
At the end of last week Trump cancelled a planned trip to Poland to commemorate the 80th anniversary of the start of the Second World War citing Hurricane Dorian.
But he has spent the last few days golfing at his own courses.
The two clashed over Trump's state visit to the UK earlier this year with the golf-loving president firing off derogatory tweets about the mayor from Air Force One hours before meeting the Queen.
Trump blasted on Twitter: "The incompetent Mayor of London, Sadique Kahn, was bothered that I played a very fast round of golf yesterday. Many Pols exercise for hours, or travel for weeks.
"Me, I run through one of my courses (very inexpensive). President Obama would fly to Hawaii. Kahn should focus on....
"....”knife crime,” which is totally out of control in London. People are afraid to even walk the streets. He is a terrible mayor who should stay out of our business!".
He later deleted the tweet and reposted it with the correct spelling.
