I will make some progress, because other Members want to speak.
There are many ways in which the Government could provide recourse to Parliament. They could table a manuscript amendment that simply puts into practice what they have said today, which would be immensely helpful and might provide the reassurance that many hon. Members need.
New clause 99 would mean that withdrawal would have to be through an Act of Parliament. On such a serious matter, there is a strong case for decisions to be made through Acts of Parliament—that would happen on other similarly weighty matters. To be honest, much of what new clause 110 would do would simply be to include in the Bill what the Minister has already said he will do. However, it would provide reassurance, with the added benefit of clarity that there will be a vote if there is no deal and we go down the WTO route. Also, the vote would be earlier in the process, which would give Parliament the opportunity to have a say before we get to the final crunch at the end of the negotiations.
The honest truth is that new clause 110 is not that radical. It would simply put into practice and embed in legislation the things that some Government Members have said they would like to achieve, so why do we not simply include it in the Bill so that we have that reassurance? Ultimately, there is a reason why all of this is important. Both sides in the referendum debate talked about parliamentary sovereignty, and with that comes parliamentary responsibility. We have already shown that responsibility by deciding to respect the result of the referendum on Second Reading, but with that comes the responsibility to recognise that we have to get the best possible Brexit deal for our whole country, rather than just walking away from the process of debating the deal. If we end up walking away, power will be concentrated in the hands of the Executive. I have never supported such concentrations of power, and every one of us should be part of making sure that we get the best possible Brexit deal.
