I thank the hon. Lady for adding to the evidence. We must listen to the evidence.
As we know, the proposals before us would require the divorce bill to be assessed by independent watchdogs, and I support that. It is important that the information that comes out of the Government’s negotiations with the EU is properly scrutinised in this Chamber and beyond. As a scientist, I learned to follow evidence. When new evidence emerges, so must our course of action change. As a doctor, if a test carried out on a patient revealed a totally unexpected result, I would repeat the test again rather than plough on with a process that I thought would harm the patient. For some years, medical professionals used to say that smoking was not a risk to people’s health, and they also used to tell pregnant mothers that moderate drinking during pregnancy posed no risk to the health of their child. With the benefit of hindsight, new information and the evidence we have now, how ridiculous do those statements seem?
We must continue to keep an open mind and to scrutinise the divorce-bill negotiations and Brexit more widely. As the opportunities seem to diminish and the potential for harm to our economy and society increases, we must also be willing to ask whether this is what the public voted for. Yes, we have a duty to act on behalf of our constituents, but as representatives, not simply delegates. I promised the residents of Stockton South that I would fight and work for them all, regardless of how they voted. The public must have the right to change their minds; that is one of the key aspects of democracy. It is
why we have elections every five years—or perhaps more often. If public opinion shifts, we must all be able to look at matters again.
Attention to detail and accountability to Parliament are crucial to the Brexit process, and particularly the divorce bill. That is why I shall support new clauses 17 and 80 tonight.
