John Kelly to leave the White House at the end of year

John Kelly will leave his job as chief of staff at the end of the year, Donald Trump announced on Saturday, describing him as "a great guy".

Mr Kelly, 68, took over from Reince Priebus in July 2017, and was brought in to try and instill some discipline in the White House.

However, his departure had long been rumoured, with Mr Kelly, a retired Marine general, reportedly frustrated at Mr Trump's freewheeling style.

Last month Melania Trump, the first lady, reportedly demanded Mr Kelly be fired.

"John Kelly will be leaving at the end of the year," said Mr Trump on Saturday afternoon, shortly before leaving the White House for Philadelphia.

"A great guy.

"We'll be announcing who will be taking John's place - it might be on an interim basis.

"He's been with me almost two years now.

"I appreciate his service very much."

Among those believed likely to take on the challenging role is Nick Ayers, the current chief of staff for Mike Pence, the vice president.

Mr Ayres, 36, is said to have the support of the president's daughter, Ivanka, and her husband Jared Kushner.

Mick Mulvaney, the budget and management director, has also been mentioned as a possible contender.
