Joe Biden will confront Liz Truss over her plans to override the Northern Ireland protocol at their US meeting, having already clashed with her over economic policy.
The White House said the US president will tell the prime minister to ensure there is “no threat” to the Irish peace process from the flashpoint legislation to rewrite the Brexit agreement.
“The president will communicate his strong view that the Good Friday Agreement, which is the touchstone of peace and stability in Northern Ireland, must be protected,” it said.
