I've just swum the length of the Thames. I feel quite tired.

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.

It's strange how sometimes you can be so happy it goes all the way round to sadness.

I think comedy is a bit more international than people credit. I happily watch lots of American shows and American comedy films. If I did a list of the top 10 comedy films in Britain, there's no sense that it would probably be different than yours.

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 used to have a silk dressing gown an uncle bought in Japan and when I came downstairs in it, my dad used to call me Davinia. There was never embarrassment about that kind of thing. My sister used to dress me up a lot. She thought I was a little doll.

I was depressed as a child. I found it hard to make friends. My favourite thing was locking myself in the bathroom and practising comedy routines.
