Boris Johnson has spoken to Donald Trump’s Vice President-elect in what is thought to be one of the US politician’s first calls to a foreign ally.
Mr Johnson, who previously criticised Mr Trump as "out of his mind", said the conversation underlined the "importance of the special relationship & need to tackle global challenges together".
It comes after Theresa May also had a conversation with President-elect Trump yesterday, albeit only after reports emerged that the US leader had not made contact with the UK a priority.
After his call with Vice President-elect Mike Pence, Foreign Secretary Mr Johnson tweeted: "Just spoken to US VP-elect @mike_pence. We agreed on importance of the special relationship & need to tackle global challenges together."
Mr Johnson has previously suggested Mr Trump is "out of his mind" after suggesting a ban on Muslims entering the US and "unfit" for office.
But after the election result, Mr Johnson insisted the UK should be optimistic about the future, adding that he is "overwhelmingly positive about the possibilities".
After other EU leaders met for a crisis meeting in the wake of the shock US election result, he told them: "It's time that we snapped out of the general doom and gloom about the result of this election and collective 'whinge-o-rama' that seems to be going on in some places."
Ms May and Mr Trump had a telephone conversation at 1.45pm, Downing Street said, focusing on the UK-US "special relationship" and on strengthening bilateral trade.
But it came after news that Mr Trump had already spoken with at least nine other world leaders, including Egypt, Ireland, Mexico, Israel, Turkey, India, Japan, Australia and South Korea, before speaking with Ms May.
Meanwhile, Downing Street has rejected the idea that ministers may use Nigel Farage’s links to Mr Trump to build bridges with the next US President.
The Independent reported earlier this week that Mr Farage will likely become the first British politician to meet Mr Trump when he visits the US at the weekend.
