Sinn Féin has refused to meet Prime Minister Boris Johnson on his visit to Northern Ireland.
The party described his trip on Friday as a publicity stunt.
Mr Johnson said he was "always happy to meet all sides" but had been told Deputy First Minister Michelle O'Neill of Sinn Féin was "otherwise engaged".
First Minister Arlene Foster urged him ditch what she called the "intolerable" post-Brexit arrangements known as the Northern Ireland Protocol.
It came into effect in January as part of the Brexit deal and means Northern Ireland remains in the EU's single market for goods, while the rest of the UK has left, so checks are required on some goods crossing the Irish Sea.
