David Camreon also lost a child. The big difference seems to be that DC is not using the death of his child for commercial and political gain.
I do belive that the tears shed by GB are genuine, as they would be by any father, but who has either decided to, or let himself be led into, using the death of his child as a way to garner favour with the tabloid media.
As a Dad i feel pity for the man who has lost a child, regardless of who he is; but to see the dead kid being used as a vote grabber is just wrong. He's not some Z-lister celeb trying to sell a cr@p book about 'his journey so far', he's the Prime Minister for christ sake!!
