Unionists have criticsed Joe Biden after his limousine was pictured flying the Irish flag in Dublin but not the Union flag in Belfast.
The US president was accused of being ‘anti-British’ by some Unionists who argued that the display showed his allegiance was to the Irish Republic, the Daily Mail reports.
When Mr Biden arrived in Belfast on Wednesday evening, his vehicle – known as the ‘Beast’ – carried the US flag and the Presidential standard on its bonnet.
But after travelling south of the border to Dublin several hours later, his Presidential Standard had been replaced with the Irish flag.
Mr Biden, who spent more time in Ireland, also posed for a selfie with former Sinn Fein president Gerry Adams and encouraged the UK to co-operate more closely with Ireland on Brexit.

Speaking to GB News, former DUP leader Arlene Foster, said: “I hope it’s not the case that he does not recognise Northern Ireland’s case within the United Kingdom which, of course, is part of the Good Friday Agreement.
“Joe Biden’s record (on Northern Ireland) has not been even-handed and I think that must be acknowledged.”
Ex-leader of the Conservative Party Sir Iain Duncan Smith claimed that the president’s choice of flags for his limousine was “further evidence of Biden’s dislike of Britain”.
He said: The Government should have insisted that he fly the Union flag in Belfast… whether he likes it or not.”
Biden administration official Adrienne Watson said: “We were sensitive to protocol and custom throughout our trip to Northern Ireland. The President looks forward to returning to the United Kingdom on a future visit.”
In a speech to the Irish Parliament earlier this week, Mr Biden spoke about the Good Friday Agreement.
He said: “Peace is precious. It still needs its champions. It still needs to be nurtured.”
The Good Friday Agreement, he said, had a “significant positive impact across the Republic of Ireland as well”.
