DIDO HARDING

I've stood in front of 500 extremely angry people in Waterford when we closed a call centre there. That's not fun, and the day you think it is fun is the day you shouldn't be doing it.

Digital safety is no different to physical safety. You can do your upmost to minimise it. You can arm yourself to protect yourself, but in the end there are criminals everywhere and that's the way of the world.

I enjoy being slightly scared.

It is generally deemed acceptable to shuttle children and adults between London and Somerset every week, but the considered view is that it would be very cruel to do the same with a dog.

I made a really stupid promise to my husband in my early 20s, when he and I were first going out, that I would retire as a jockey when I was 40.

Competition drives growth in the end as opposed to monopolies.

It is not often that one of the world's best entrepreneurs rings you up and says 'I've got this business we are about to float off as an independent company and we'd like you to be chief executive.'

I'm a really big believer in chief executives not staying forever.

You have to have a thick skin if you think what you are doing is right.

But I was an utterly hopeless politician and I worked out that I would be much better suited to making money and running businesses than the compromise that is politics.

I have no hesitation in challenging government of whatever party.

I was that sort of obnoxious girl, I remember being 10 at careers things where people were talking about becoming secretaries and I said I don't want to be a secretary, I want to have a secretary, and people would sort of look at me slightly perplexed.

We don't have very many nights out on our own, and by most people's standards we don't have much of a social life. But for us the compromise works, and I think the best thing I ever did was to have a family.

It's not a normal thing to receive a ransom demand in your inbox. I felt physically sick.

I think we'd be cutting off our hand to spite our face if we demonize private health care.

I think that Britain's broadband vision needs to be about more people using broadband rather than macho claims about the speed of the technology.

I have an enormously privileged position. I make a lot of money - a matter of public record - I have a huge amount of help, and I'm more in control of the day and what I do than someone working shifts on the checkout, or running the produce department in a supermarket.

Unfortunately cybercrime is the crime of our generation.

Often when websites start running slowly, it's because they're under some form of attack.

I've always been of the view that two-term presidency rule is a pretty good one and CEOs shouldn't overstay their welcome.

I miss the racing hugely. If you told me I could go off and do it tomorrow afternoon I would. For me that's always been my way of shutting everything off and relaxing.

TalkTalk's culture is one of a start-up... new services, desire to innovate, move fast.

If I only had one day left in my life and it was riding a race or owning the Gold Cup winner, I'd ride a race.

Every single company knows that there is more that they can do to keep themselves safe from cyber-crime.

I'm still here, living proof that sometimes it's OK to admit to your fallibility.
