President Trump fired his secretary of state this morning, soon after Rex Tillerson had stood shoulder to shoulder with Britain and broken with the White House by denouncing Russia for the poisoning of Sergei Skripal, the former MI6 agent.
Mr Trump said that Mike Pompeo, director of the CIA, will be his new secretary of state.
Mr Pompeo is considered to be a Trump loyalist.
It had been rumoured for months that he was set to replace Mr Tillerson, a former oil executive who had clashed with Mr Trump on a host of issues, including the Paris climate accord, the Iran nuclear deal and how to contain North Korea.
His last official trip was in Abuja, Nigeria with President Buhari.
