What has David Cameron's wife Samantha said about their son Ivan dying?
Samantha Cameron said in an interview with the Times newspaper that her son's death was "such a massive thing that everything else is irrelevant". She said: "I think it changed Dave's politics. It made him understanding, though he couldn't be too subjective.... From the moment he is born, you are living in a situation that is quite surreal and difficult to deal with... It is intense every day, in and out of hospitals... in a way, that prepared me for Dave being prime minister, because I was used to living and operating in a way that's not normal... Like anyone else in my situation, I just kept going. You have to deal with it, because you have no choice."
