President Donald Trump has spent 22 per cent of his time in office on the golf course so far, new research has found.

An NBC News tally discovered that Mr Trump has spent 37 days out of his total 170 days on the golf course.

The President was in Virginia for the 37th golfing trip on Sunday after he returned from the G20 summit in Germany.

He has also used 51 days of his presidency at Trump properties around the US.

On the campaign trail, he urged Americans to vote for him as he would rarely leave Washington DC or go on holiday due to the workload of the presidency.

“I love golf but if I were in the White House, I don’t think I’d ever see Turnberry again,” he said last year.

“I’d just want to stay in the White House and work my ass off.”

His next golfing trip is expected to be at one of his two courses in Scotland, one of which is Turnberry in Ayrshire, when he flies back to Europe to celebrate Bastille Day in France on 14 July.

The President has devoted the most golfing time to the Trump International West Palm resort, near his Mar-a-Lago home, where he has often spent weekends.

He also consistently attacked his predecessor, Barack Obama, for taking golfing trips, yet Mr Trump has frequented the golf course more.

The number of golf trips has not been transparent as the press pool was often kept away from the course and the administration would refuse to confirm if the President was playing sport.

People resorted to social media, sharing photographs and tweets, to confirm the President's whereabouts.

His trips have cost the taxpayers millions of dollars due to the cost of Air Force One transport, secret service, coast guards and other agencies.
