Republican presidential candidate Donald Trump has overhauled his campaign team for the second time in two months, with two new leaders.

Trump has seen his poll ratings slip since the party conventions last month.

He trails Democratic Party candidate Hillary Clinton both nationally and in key battleground states.

The latest shake-up comes just 82 days before the election.

The Associated Press news agency said the details of the new hierarchy were hammered out at a lengthy senior staff meeting at Trump Tower on Tuesday and that more senior appointments were expected in the coming days.

The new appointments come ahead of the Trump team’s first major TV advertisements, due to start this week.

Trump has been pressed by some Republicans to tone down his fiery rhetoric in the wake of a number of controversial comments in the past two weeks and the subsequent drop in poll ratings.

But Trump appears to want to stand by the campaign style that won him the Republican nomination.
