The next Brexit battle is here
Spectator (UK)APR 3 2022
The government is risking a trade war to relieve the pressure of internal party divisions. This reckless provocation might be successful in appeasing Euroceptic Conservatives and strengthening Johnson's position following a catestrophic no-confidence vote, but Tory MPs are now committing the UK to unlawful legislation and asserting its legitimacy brazenly and without compunction.
Changing the NI protocol will not break the law. Treaties are agreements that come under particular jurisdictions, not laws that are enforced by authorities. As long as Boris Johnson passes any changes to the post-Brexit trade agreement through parliament - which he's doing - he's altering the law, not breaking it.
