In the run up to the General Election, five special Tonight programmes will take an up close and personal look at the lives of the leaders of the largest political parties in Britain.
The first profile sees ITV News' Political Editor Tom Bradby spending time with Prime Minister David Cameron and his family.
Speaking in the family home at Downing Street, Samantha Cameron reveals how she was "terrified of the impact [life at No10] was going to have on the children" as well as her marriage and family life.
But she added: "It's been much easier than I expected it to be, I go to the same office, the children go to the same school. There's a lot of our life that hasn't changed".
She also revealed how the family remain "grounded" despite their lives in the spotlight.
We have a lot of focus on being on our own, keeping up with old friends, we’ve got big families. I am one of eight siblings, he’s one of four and I think that keeps you grounded. You’ve got to try and, you know, not let your life change in any way.
David Cameron speaks candidly about the “dread” of losing his oldest son, Ivan, in 2009.
Look, it's everyone's dread to lose a child, that you out-live your children. You lose someone you love so much, so young. It does hit you like nothing else and there is a bit of you that thinks well, if you can face that sort of challenge in your life, then it puts everything else into perspective.
Mr Cameron also opens up about the pros and cons of being Prime Minister and his thoughts about when he should give the job up.
Four and three quarters years in, I feel I'm doing a good job, I've got a strong team. I know what I need to achieve, I know where the country is going. I really want to finish the work. But I totally recognise, there is a time when you will have given your best, and it's time for fresh blood and new people and all the rest of it. Hopefully you stay sane for long enough to realise when that is.
Tonight: Spotlight - David Cameron, will be broadcast Tuesday 7th April at 7.30pm on ITV
