Donald Trump is considering a major shake-up of his top team, with both Steve Bannon and Reince Priebus reportedly facing "reassignment" amid intense infighting at the White House.

The US president is said to be determined to end the simmering feud within the West Wing that pits Mr Bannon and his allies against Jared Kushner and his wife Ivanka Trump.

The relationship between the far-Right former media executive and the president's son-in-law has deteriorated to the point of "breakdown", sources say.

The two clashed over the decision of whether or not to launch Friday's early morning air strikes against the Syrian regime, with Mr Bannon firmly stating intervention did not advance Mr Trump's " America First" doctrine, it is claimed.

The fact that the air strikes went ahead was seen as evidence of the waning influence of Mr Bannon, who had seemed untouchable at the culmination of the election campaign and early days of the presidency.
