Theresa May has written to formally congratulate Donald Trump on becoming US president.
The letter stressed the special relationship between Britain and America, said Downing Street.
"Her letter reaffirmed the strong ties that exist between Britain and the United States, which are based on the values of freedom, democracy and enterprise, and she spoke of our close partnership on trade, security and defence," the Number 10 spokesman said.
The Prime Minister said she aimed to speak with the president-elect "at the earliest possible opportunity" to discuss the "special relationship" between the US and the UK.
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?
