I'm not embarrassed about the novels I wrote when I was younger, but I couldn't write them today because of my religion.

I was educated privately for free because I was a scholarship girl, 100% scholarship girl. I got it on my own merits. I would never dispute that I am a privileged person. Nevertheless, when I started work I made 11 grand a year. I got my book deal on my own, my father didn't write those books for me, I did all of that entirely on my own. I stood for parliament with the amazing support and help of my ex-husband, but it's not something that was handed to me like a peerage. I worked hard and was elected. So my achievements, such as they are, are my own.

Yes, I know, shaming, isn't it? I always say you can take the girl out of the 80s, but you can't take the 80s out of the girl. Before I wrote my first novel, I was reading one of the self-help classics – and it's as cheesy as you like, so feel free to laugh, Guardian readers – called Awaken The Giant Within, by Tony Robbins, and it inspired me to try. I like motivational books, because I like the go-getting American spirit – your destiny is in your own hands, life is what you make it, don't accept your limitations, jump before you're pushed, leap before you look.

Your moral stance depends on what you think is being aborted. If you don't believe it to be a person but part of a woman's body, of course you will be pro-choice. I would be virulently pro-choice if I didn't believe it to be a person.

'Kane and Abel' is the best popular fiction of all time. As a kid, I wanted to be prime minister when I read 'First Among Equals.'

Menshn is a play on the word mention, and in the U.S. that's how it'll be perceived. Like Tumblr or Flickr. People in the U.K. thought that I'd named it after myself.

We'd all survive if Twitter shut down for a short while during major riots. Social media isn't any more important than a train station, a road or a bus service. We don't worry about police temporarily closing those. Common sense. If riot info and fear is spreading by Facebook and Twitter, shut them off for an hour or two, then restore.
