UK government has been asked to veto EU law update applying in Northern Ireland relating to chemical labelling

Keir Starmer is facing his first major test over Brexit after unionists in Northern Ireland decided to pull what is known as the Stormont brake on EU laws due to apply in the region.

Unionist parties and independents decided to come together to exercise their right to object to an update in EU legislation which would apply to labelling on chemicals. By pulling the brake, they invite the UK government to veto a EU law applying in Northern Ireland.
