Foreign Secretary Boris Johnson will not attend a European special meeting called to discuss Donald Trump's US election victory.Mr Johnson has told his EU counterparts to end the "whinge-o-rama" over the result of the presidential race.
A Foreign Office spokesman said he would not go to the meeting on Sunday but would attend a regular Foreign Affairs Council meeting on Monday.
The BBC understands a senior UK official will be sent in his place.
A Foreign Office spokesman said: "The Foreign Secretary will not attend the meeting convened for Sunday. There is a regular Foreign Affairs Council meeting on Monday where a range of issues can be discussed in the normal way.
"We do not see the need for an additional meeting on Sunday because the US election timetable is long established. An act of democracy has taken place, there is a transition period and we will work with the current and future administrations to ensure the best outcomes for Britain."
On Friday Mr Johnson said "with respect to my beloved EU friends and colleagues, I think it is time we snapped out of the general doom and gloom about the result of this election and the collective whinge-o-rama that seems to be going on in some places".
Mr Johnson's remarks are in stark contrast to those of EU Commission President Jean-Claude Juncker.
He said Mr Trump's election risked upsetting EU ties with the US "fundamentally and structurally".
He said: "We will need to teach the president-elect what Europe is and how it works", adding that two years would be wasted while Mr Trump "tours a world he doesn't know".
Following his victory Mr Trump spoke with Prime Minister Theresa May. A Downing Street spokesman said they agreed that "the US-UK relationship was very important and very special and that building on this would be a priority for them both".
But a senior member of German Chancellor Angela Merkel's Social Democrat coalition partner, Axel Schafer, said the PM's hope that Mr Trump will look favourably on the UK will come to nothing.
Mr Schafer told The Times: "What changed is the likelihood of a speedy and preferential trade deal between the UK and US. Even before Tuesday the chances were rather low, now the hope for this kind of deal seems delusional."
