I love Paris for its wide boulevards and cafes, and Rome for the ancient history, as seen at the Forum.

Once I was on a plane and a woman said to me, 'Now, what's the matter with my tomatoes?' And I said, 'Well, it's a bit difficult to see from here.' She took offence and said, 'I was only trying to be friendly.'

I'm a big fan of the Queen. She carries herself well, as does the Prince of Wales, despite getting lots of stick.

I don't like people being rude. Bad manners and arrogance make me cross. People making others feel uncomfortable. And I really don't like it in restaurants when people are rude or patronising to waiters. I feel like saying, 'They're not your slave'. But my knees only shake around once every five years. You're safe, don't worry.

My wife and I always have a winter holiday that I call the "fly and flop". In January and February, you don't want culture, you just want to get your bones warm and eat, drink, sleep. We usually go to the Caribbean.

You hope people won't be tricky or miserable. If you're in public life, it's important not to be. If someone says, 'I like your programme, thank you,' you should be grateful. I am. Why be nasty?

I get nice letters, but really I have no idea. I just try to enthuse people. You've been married for 31 years.
