I congratulate the hon. Gentleman on crowbarring Brexit into that question. Most people appreciate that the existing channel tunnel is likely, at the current rate, to be full within the next seven years, which is a very short time in the lifetime of a great infrastructure project. It is a curiosity that two of the most powerful economies in the world, separated by barely 21 miles of water, are connected by only one railway line. I think that is a matter for legitimate reflection by our two countries on the way forward.
