Steve Bannon: the de facto president?
Among the most powerful people in Donald Trump's inner circle is his chief strategist, Steve Bannon. Many have questioned Mr Trump's controversial appointment of the man behind the right-wing Breitbart News website. Mr Bannon has been swiftly promoted to one of the highest levels in the government: a permanent seat on the White House National Security Council.
So, where does the balance of power really lie?
