evidence: Having barely entered into force, the protocol has been held responsible for supply difficulties in Northern Ireland and has also given rise to tensions between the European Union and London. After the launch of a unilateral review of Northern Ireland's post-Brexit status, the European Commission initiated a series of proceedings against London. The protocol has mostly become an internal problem for the government of Rishi Sunak, who faces opposition from Brexit hardliners and the unionists of the Democratic Unionist Party (DUP), who are fiercely opposed to any questioning of Northern Ireland's membership in the UK. [...] The retention of certain European laws and the jurisdiction of the European Court of Justice in Northern Ireland was one of the main sticking points of the protocol for the unionists. The Windsor Framework provides for the creation of a "brake" available to the Northern Ireland Assembly. If 30 MPs from different parties object to the implementation of a new European law on goods in the province, they will be able to call a vote to block it, modeled on a provision that already exists in the 1998 peace agreement.
