Anthony Scaramucci was brought in to be the new face of an embattled White House, the man to put a fresh gloss on its missteps and controversies.

Yet after only a week into the job he is threatening to sack his entire staff as he hunts for leakers and has been caught badmouthing both the White House chief of staff and Donald Trump's chief strategist.

Rather than cleaning up the mess, he has exposed the administration's divisions to the world and ensured the behind-the-scenes tension explodes into a public war.

On Thursday morning he appeared on TV to all but accuse Reince Priebus, the chief of staff, of leaking against him. Hours later details emerged of an extraordinary telephone conversation with a journalist in which he launched a foul-mouthed tirade during which he said that Mr Priebus would be soon be asked to resign.

The day began with an unscheduled interview on CNN, prompted by his decision to call in by phone.

“The fish stinks from the head down. But I can tell you two fish that don't stink, and that’s me and the president," he said, casting doubt on the rest of the staff and their motives.

It was the latest salvo in his hunt for the source of White House leaks. It is a cause close to the president's heart and Mr Scaramucci has made it clear that he answers only to Mr Trump.

He appeared to point the finger Mr Priebus, first in a rapidly deleted Tweet on Wednesday.

Then he further fanned the flames on CNN a day later, challenging Mr Priebus to deny he was the source.

“When I put out a tweet and I put Reince's name in a tweet, they're all making the assumption that it's him because journalists know who the leakers are," Anthony Scaramucci said during the unscheduled 30-minute interview.

"So if Reince wants to explain he's not a leaker, let him do that. But let me tell you about myself. I'm a straight shooter and I'll go right to the heart of the matter."

His relationship with Mr Priebus was already fraught before he was appointed last Friday. The chief of staff was among the voices urging Mr Trump not to bring the Mooch, as he is nicknamed, into the White House earlier.

The latest spat was sparked by publication of an official document detailing Anthony Scaramucci’s finances, even though it is available to anyone who asks.

On Wednesday evening, Mr Anthony Scaramucci was further angered when a reporter obtained details of a White House dinner.
