Reuters reports that Irish Prime Minister Micheal Martin said that U.S. President-elect Joe Biden wanted a Brexit trade deal to be clinched with the European Union so British Prime Minister Boris Johnson should knuckle down and strike an agreement.

Biden's win in the U.S. presidential election has changed the international context of Brexit: The United Kingdom's most powerful ally will now be led by a man who favours a Brexit deal and relishes his Irish heritage.

"He is very committed to the Good Friday Agreement," Martin said of Biden. "Particularly in relation to Brexit, he would favour obviously a deal between the European Union and Britain."

"And I think that's where, if I could respectfully say it, that's where the British government should head, in that direction, in my view. It should knuckle down and... get a deal with the European Union," Martin told BBC radio.
