"Many people would like to see @Nigel_Farage represent Great Britain as their Ambassador to the United States. He would do a great job!" Trump tweeted Monday evening.
Although it is unusual for an incoming president to suggest ambassador choices for other countries, it is perhaps unsurprising in this case, due to Trump's friendly relationship with the UK Independence Party (UKIP) leader.
The two have grown especially close in recent months, with Farage becoming the first foreign politician to visit the president-elect, arriving at Trump Towers just three days after the November 8 election.
In a tweet following that meeting, Farage praised Trump's "good ideas" and expressed confidence in the next leader of the United States.
Farage also campaigned for Trump in Mississippi in August, and is expecting an invitation to his inauguration in January, a source told the Guardian.
Trump repeatedly compared his campaign to the UK's historic Brexit decision, often mentioning Farage – the major voice behind the push to leave the EU – at his rallies and referring to himself as 'Mr. Brexit.'
But Trump's recommendation could create waves on both sides of the Atlantic.
In the UK, Prime Minister Theresa May rejected Farage's offer to act as a go-between in her relationship with Trump. Number 10 stated that the government already has "well-established" lines of communication with Washington.
In the US, Trump's support for Farage becoming the UK ambassador will likely be unsettling to the current holder of the post, Sir Kim Darroch, who has only held the position since February.
