There is no good reason for the UK to sabotage relations with its European neighbours, but doing it to score ideological points with a small faction of the prime minister’s supporters is exceptionally poor judgment. Yet that is what Boris Johnson intends to do with legislation, now said to be due for publication next week, to override the Northern Ireland protocol of the Brexit deal he signed in 2019.
The ostensible trigger is the collapse of power-sharing at Stormont, caused by the Democratic Unionist party’s refusal to form an administration with Sinn Féin. The DUP objects to the basis of the protocol – the requirement for customs checks on goods crossing the Irish Sea – and wants it rewritten. The EU offers modifications in the way that the treaty is implemented, saying checks are necessary to prevent Northern Ireland becoming an unregulated backdoor into the single market.
