US President Barack Obama and President-elect Donald Trump have both stressed the need for a smooth and calm handover of power as they met face-to-face for the first time.
After a meeting at the White House, which must have been slightly awkward given their previous harsh words during a bitter campaign, Mr Trump and Mr Obama were able to hide any animosity and spoke of their mutual respect.
"President Obama came away from the meeting with renewed confidence in the commitment of the President-elect to engage in an effective, smooth transition," White House spokesman, Josh Earnest, told a news briefing.
Donald Trump's campaign was decidedly unflattering towards Mexicans - but there is hope over the border his words will not amount to action.
Donald Trump alluded to the good relationship enjoyed by Ronald Reagan and Margaret Thatcher in his phone call with Theresa May.
Following the election of Donald Trump in the US presidential election, can the special relationship between the UK and the US continue?
