Donald Trump today attacked Sadiq Khan as a 'stone cold loser' in a new war of words between the US President and London mayor.
Mr Trump fired off a fresh Twitter volley minutes before landing at London's Stansted Airport ahead of an official state visit.
Mr Khan yesterday criticised the UK government for rolling out the red carpet. He said the visit would be viewed in the future with 'profound regret'.
The President's plane Airforce One was minutes from touchdown when he tweeted his latest barbs.
He accused Mr Khan of doing a 'terrible job' as Mayor of London and being 'foolishly nasty' in his attitude to a visiting president.
He also made an unfavourable comparison between Mr Khan and New York mayor Bill de Blasio.
