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.

I'm definitely a Tory. My dad was a Conservative councillor, and I spent years as a child knocking on doors with him. I'm a Tory because I'm passionate about business and enterprise. But I am also a compassionate Conservative. There should always be a net through which no one should fall.

As a small business owner for the last 15 years, when I think of what truly changed my life, it was my faith, a strong family, my mom did a really, really good job of encouraging me in very clear and discernible ways.
