I am just going to make some progress.
Lords amendment 19 is of critical importance. In many ways, it is the most important amendment that we will consider over the 12 hours allotted. Before I explain why and set out the reasons why we agree with Lords amendment 19 and disagree with the Government’s amendment (a) in lieu, it is worth taking a little time to remind the House how we arrived at this point.
As hon. Members may recall, before 7 February last year Parliament was to be given absolutely no role in approving the final terms of the UK’s exit from the EU, because there was no commitment from the Government to a parliamentary vote of any kind. Under pressure, the then Minister, the right hon. Member for Clwyd West (Mr Jones), came to the Dispatch Box during the Committee stage of the European Union (Notification of Withdrawal) Bill with a concession—a vote on a motion in this House and the other place on the article 50 deal, including the framework for a future relationship. We welcomed that concession, but we were clear that it did not provide for a meaningful vote, merely a vote on a non-binding motion and one that would essentially take the form of “take it or leave it”—accept the final draft withdrawal agreement, even if it is found wanting, or accept that the UK will walk away without a deal, triggering the hardest of departures from the EU.
