My Lords, this amendment also bears my name and the names of other noble Lords. I will focus my brief remarks on
the eventuality of the United Kingdom facing the prospect of leaving the EU in March 2019 without any deal having been reached between the EU and the UK on the terms of a withdrawal treaty, or on the framework for a new relationship between them. I will, too, set out a pretty compelling case for this eventuality to be covered if a parliamentary approval process is to be genuinely meaningful.
This House is no stranger to debate on the no-deal situation. When we considered the Bill authorising the Government to trigger Article 50 before the end of March 2017, we voted by a substantial majority for a meaningful process that covered the no-deal eventuality. The other House, where at that time the Government had a single-party majority, rejected that amendment, and we did not insist. We must, however, face the fact that this Government have never made any commitment to give Parliament any say on a no-deal outcome, although they have committed themselves—rather inadequately—to giving Parliament a say if a deal is struck. The rest of this amendment deals with those circumstances. In the no-deal scenario, there is a void—a vacuum. That is not really tolerable for such an eventuality.
I do not intend to speculate about what circumstances might give rise to this eventuality—that would be a bit of a mug’s game six months before the end of a negotiation. The Government seem to have put away their rather foolish mantra that no deal is better than a bad deal, which I welcome. Suffice it to say that until the final moment of the Brexit negotiations, no deal remains a possibility and needs to be provided for in any meaningful process of parliamentary approval.
On the substance of no deal, I say only that there is now a much wider understanding of the fact that it would be seriously damaging to our economy, as we fell back on WTO terms. The Business Committee of another place brought that out very cogently as recently as last week. There are plenty of other disadvantages outside the trade field if we were to find ourselves going over a cliff edge in March 2019, but this is not the occasion nor the time to have that debate about what the consequences of no deal would be. What needs to be debated today, and I hope decided, is to set out the fact, as subsection (8) of the proposed new clause provides, that Parliament and not the Executive needs to be the ultimate arbiter in such circumstances. I hope that we will establish that in this House at the end of this debate.
