Theresa May should not trigger article 50 alone – formally starting the UK’s exit from the European Union – without “explicit parliamentary approval”, a parliamentary committee has warned.
In a direct challenge to Downing Street’s authority over Brexit, the House of Lords constitution committee has published a report declaring that it would be “constitutionally inappropriate” for the prime minister to act on an advisory referendum without referring back to parliament.
The report says: “In our representative democracy, it is constitutionally appropriate that parliament should take the decision to act following the referendum. This means that parliament should play a central role in the decision to trigger the article 50 process, in the subsequent negotiation process, and in approving or otherwise the final terms under which the UK leaves the EU.
