On a point of order, Mr Speaker. We live in interesting times, if I can put it that way; we are in a constitutional crisis. We are aware that the Prime Minister is going off to Brussels tomorrow, and out of that we will learn whether we are going to have an extension to article 50. We need to reflect on the fact that we are a week away from the intended departure date from the European Union. The threat of no deal from the Government is very real, and we ought to be aware of the consequences. The Government have told us about the threat to the supply of medicines, to food supplies and to public order. These are serious matters, and given that we have very few days left, I have today written to the Prime Minister and demanded that, in the circumstances, this House should convene on Saturday so that we can plot a way ahead. We need to use the opportunities granted to us in these few days that are left, and we might indeed need to use the opportunity to revoke article 50 if the Government are serious about taking us forward on a no-deal scenario. Mr Speaker, I ask your forbearance, and I ask what opportunities you can suggest that are open to us to ensure that, in these times of crisis, we have the opportunities that we had at the time of the Suez crisis—the last disaster visited upon us by this Government—to ensure that we can stand up for our constituents and protect our people from the catastrophe of no deal.
