Joe Biden was confused over Rishi Sunak's title when the pair met within the White House by welcoming him as "Mr President" in an embarrassing gaffe. The US President swiftly corrected himself, joking he had "promoted" Mr Sunak. Mr Biden, 80, seated throughout from Mr Sunak for the bilateral assembly, stated: "Well, Mr President - Mr President, I just promoted you. Mr Prime Minister, it's great to have you back."

Mr Sunak, who laughed off the error, has not been to the White House earlier than as prime minister, having solely taken workplace in October.

Mr Biden advised him: "In the past few months we have met each other in San Diego and then we met in Belfast and we met in Hiroshima.

"And now we're right here we're going clear up all the issues of the world within the subsequent 20 minutes."

This will not be the primary time the US President has appeared to fumble his phrases.

During his go to to the Republic of Ireland in April, Mr Biden appeared to confuse the identify of the New Zealand All Blacks rugby crew with the Black and Tans - a controversial War of Independence-era police drive in Ireland.
