When you are doing endurance swimming you just need to take in as many carbs as possible to put on as much weight as you can. Basically you can eat whatever you want, which can be quite fun. Everything is guilt-free.

I'm not a political thinker, but I've just always thought of myself as a Labour supporter. I was a great fan of Tony Blair. He sent me a letter before I swam the Channel to wish me luck.

We sit in a room for months trying to think of funny things.

I still enjoy my life, and I feel like I've achieved enough things that if I never did anything again, I'd feel confident that I'd still have made my mark in some way. But maybe the self-loathing bit is the element that makes you strive for more. Makes you strive to be better.

I was quite fat as a kid. And swimming is a sport you can enjoy whatever size you are. If you're fat, running is a pain. I'm not really built for running.

In Britain, a cup of tea is the answer to every problem. Fallen off your bicycle? Nice cup of tea. Your house has been destroyed by a meteorite? Nice cup of tea and a biscuit. Your entire family has been eaten by a Tyrannosaurus Rex that has travelled through a space/time portal? Nice cup of tea and a piece of cake. Possibly a savoury option would be welcome here too, for example a Scotch egg or a sausage roll.

I can't see why anyone would want to be in politics because you get so much criticism.
