President Donald Trump has returned to the White House with an Oval Office renovated entirely to his specifications.

When he took over on January 20 some alterations were immediate – the president “was delighted to page through a book that offered him 17 window covering options,” the New York Times reported at the time, and was “obsessed with the décor” of his new office, asking staff to schedule televised events in the famous room.

The bust of Churchill, controversially removed by Mr Obama and replaced with Martin Luther King, was immediately brought back by Mr Trump.
