The Senedd voted to withhold consent to part of a UK trade agreement bill due to the “threat” posed to Wales’ constitutional principles and devolution settlement.

Mick Antoniw raised concerns about the Trade bill, which aims to ensure the UK complies with the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP).

Wales’ constitution minister warned that clause two of the bill – on product conformity checks – undermines the devolution settlement and allows the UK Government to act unilaterally.

Mr Antoniw, who is also counsel general, the Welsh Government’s chief legal adviser, said UK ministers maintain that clause two falls within powers reserved to Westminster.
