Helen was granted an Urgent Question on seeking Parliamentary approval before triggering article 50 this afternoon.
Helen asked John Penrose MP, The Parliamentary Secretary, Cabinet office
"If he will make a statement on whether the Government will seek parliamentary approval before triggering Article 50."
Helen continued by arguing that to use the royal prerogative to activate Article 50 would be "a breach of promises made to the public" by Leave campaigners who said they would "take back control and restore parliamentary sovereignty".
Such an important step "should not be decided behind closed doors in Whitehall while Parliament is presented with a done deal", she said.
