Mr Biden was welcomed by Mr Sunak as he arrived in Belfast late last night. The president is due to deliver a speech about the Good Friday Agreement at Ulster University’s new Belfast campus this afternoon before heading south of the border.

Amnesty International has called on Mr Sunak to use the occasion to scrap the Northern Ireland Troubles (Legacy and Reconciliation) Bill and recommit to realising the human rights protections central to the Good Friday Agreement.

“Biden and Sunak’s meeting is a key moment to acknowledge the Good Friday Agreement’s achievements, but we cannot ignore the reality of UK government actions that recklessly undermine it,” Grainne Teggart, Amnesty’s Northern Ireland deputy director, said.

“It rings entirely hollow that the prime minister is celebrating the Agreement whilst simultaneously pursuing a legislative agenda that erodes the rights commitments central to it.

“The prime minister must scrap the widely-opposed Troubles Bill that violates the Good Friday Agreement, and end threats to the European Convention on Human Rights which has been a cornerstone of Northern Ireland’s peace settlement.”

Mr Biden will be in Ireland until Friday and is expected to meet the Irish president and address the Oireachtas on Thursday.
