Donald Trump overhauls campaign team

Republican Donald Trump has announced a shake-up of his campaign team leadership amid falling poll ratings 81 days before the presidential election.

The billionaire property mogul has named Stephen Bannon, of the conservative Breitbart News website, as chief executive and promoted pollster Kellyanne Conway to campaign manager.

Paul Manafort, Mr Trump’s controversial campaign chairman, will retain his title but it is unclear if his role will change.
