Looking after a disabled child pushes you to the limits of what you can cope with... physically, emotionally. It's because there's this baby, this child that you love more than you can possibly imagine, in some way more than a normal child because you worry about them 24 hours a day. But at the same time you are so, so proud of them.

The truth is I am not a very hands-on political wife; I don't get involved in day-to-day Downing Street life. They don't need me interfering, but in the evening, we will talk about each other's day. I try to stay out of the Westminster village. There are times when I will be surprised and curious about what's been announced.

What I look for when I see a piece of art for the first time is some kind of emotional, intellectual experience, that's a combination of both of those things and is informed by my knowledge and something new that I see the artist doing.
