The Brexit Secretary said the electorate “will not forgive” Labour if it disrupts the process of leaving the EU, slamming its stance as a “cynical political exercise.”

But Mr Starmer accused him of a “power grab” that would hand “sweeping powers” to ministers, letting them “bypass Parliament” on the form our departure from the EU takes.

Mr Davis pretended the Bill was “a technical exercise converting EU law into our law without raising any serious constitutional issues,” his opposite number said, but instead it gave “the widest possible power” to the government with “no safeguards.”
