Unionist parties from Northern Ireland to take legal action against the Brexit deal

Members of Northern Ireland’s Democratic Unionist Party (DUP) and Ulster Unionist Party (UUP) announced Sunday to take part in legal action challenging part of Britain’s deal with the European Union.
The Protocol agreed during Brexit is designed to protect the European Union's single market without creating a land border on the island of Ireland but so far caused disruption to trade since it came into force at the start of the year. Some British companies have halted deliveries to Northern Ireland, and some supermarkets have been left with empty shelves.
"Alongside the political action we have been taking, we have considered a number of legal routes, and will be joining other unionists from across the United Kingdom in judicial review proceedings to challenge the Protocol, unless arrangements are put in place which are consistent with the Act of Union 1800, the Northern Ireland Act of 1998 and the Belfast Agreement. ", said DUP leader Arlene Foster.
