Mrs May will then return to No 10 as the country's second female prime minister, following in the footsteps of Margaret Thatcher.

She is expected to briefly address the nation before meeting top officials, including Cabinet Secretary Sir Jeremy Heyward, and receiving a full national security and defence briefing. She is also expected to take calls from a number of foreign leaders. Later on Wednesday, she will get down to the work of putting together her government - with key appointments set to be announced within hours.
