As the father of two young daughters, I cannot imagine losing either of them, and in that respect I have no idea what David and Samantha are going through. I can but imagine how I might be in their circumstances. Those pictures of Ivan's parents caring for him, touching him and holding him are very special indeed.
I am very rarely moved by the news, but watching the BBC tonight I admit to getting very upset indeed; a child is so precious and so wonderful that losing them at any age must be devastating. David and Samantha should thank God for his 6 years tonight and that they showered him with love and affection during that time. Ivan was in a great deal of pain, but the touch of his loving parents no doubt helped him through those times. But we should also keep Nancy and Arthur in our prayers who have lost a brother they both loved very dearly.
Our families shape us as much as we shape them; Emily and Olivia have changed me and my politics and we have heard today how Ivan changed David Cameron. Few people can ever say they moulded a Prime Minister, but I think Ivan Cameron has done it. He lived a remarkable life and both he and the Cameron family are in my prayers tonight.
