On a point of order, Mr Speaker. We are soon to start a debate on the subject of a no-deal Brexit. It may be that some Members have business interests that might benefit from a no-deal Brexit, such as companies involved in shorting the pound or the value of shares, or that might have secured payments from companies that are enthusiastic backers of a no-deal Brexit. How would you advise that those Members declare their interests?
I am grateful to the right hon. Gentleman for his point of order. The short answer is that the registration of interests is a matter for the judgment of each individual Member; no precise advice can be given to cover every eventuality. Whenever I am asked by Members for my advice, I say: if in doubt—if there is uncertainty, if they think someone might subsequently criticise—it is better to err on the side of over-declaration than of under-declaration. That has been my own philosophy, and I would commend it to colleagues. I hope that that is helpful.
