"We welcome the Supreme Court Judgment today which means that the UK Government must seek parliamentary approval in the form of a Bill before it can trigger Article 50 to leave the European Union."
A Welsh Government spokesperson said:
“We welcome the Supreme Court Judgment today which means that the UK Government must seek parliamentary approval in the form of a Bill before it can trigger Article 50 to leave the European Union. It is vital that the UK Government develops an approach to negotiations which reflects the interests of Wales and the UK as a whole – an approach to which the Prime Minister has already publicly committed.
“The judgment preserves and recognises the importance of the Sewel convention whereby Parliament will not normally legislate on areas devolved to Wales and devolved governments without their consent.
“The Welsh Government will continue to work closely with the UK Government, and the other Devolved Administrations, through the Joint Ministerial Committee process to influence the overall UK position. Our aims are to preserve single market access for business and to protect Welsh jobs and investment, along with the rights of workers.”
