I'm a trained lawyer, after all, so I don't have to admit to anything.

Schoolchildren and older people like the idea of planting trees. For children, it's interesting that an acorn will grow into an oak, and for older people it's a legacy. And the act of planting a tree is not that difficult.

If I ever had any vanity, then I definitely lost it by being on television. It doesn't do you any favours in terms of showing you what you look like and what your emotions are.

Gardening has just sort of grown on me. I find it therapeutic. And I like smelly things.

I try to make myself walk around a bit, but I probably think about it more than I actually do it. Years ago, I did think about joining a gym.

My favourite plant is the foxglove. I think they are a perfect balance between being a garden plant and a wild plant, as at home in woodland as they are in a city.

On the environmental front there's concern about global warming and high levels of carbon dioxide, and trees take in CO2 and store carbon.
