Following the U.S. President-elect Donald Trump's suggestion for British Prime Minister Theresa May, Britain rejected the notion that Nigel Farage would serve as British ambassador to the United States. British Brexit Minister Davis said that there is no vacancy as they "have a very good ambassador already."

There are a few obstacles to the president-elect's desire to have the acting leader of the U.K. Independence Party serve as Britain's chief diplomat in the United States — not only is it the role of each country to name its overseas representatives, but there is already an ambassador in place.

The highly unusual call from Trump clearly shows the scale of his liking for Farage, who played a key role shaping public opinion in favor of taking Britain out of the EU ahead of the June referendum.

Trump tweeted late Monday night that "many people" would like to see Farage head Britain's U.S. mission, adding: "He would do a great job!" Trump's tweet received a cool response in official circles. A spokesman for May said there is "no vacancy" at the British Embassy in Washington and praised the work of the incumbent ambassador, Kim Darroch.

May had earlier rejected the notion that Farage would serve in an unofficial role as liaison to Trump. The negative response prompted an angry reaction from Farage in a column posted on the Breitbart website. "At every stage I am greeted by negative comments coming out of Downing Street," he wrote. "The dislike of me, UKIP and the referendum result is more important to them than what could be good for our country."
