Of all the images on our TV screens yesterday I think there were probably few more moving than the sight of John and Fraser Brown leaving Downing Street hand in hand with their parents.
A few years ago I met Gordon Brown and he revealed he'd put up a climbing frame for his sons in the garden of No 10. 'We have trouble getting them off it and persuading them to go to bed,' he told me.
I know a few people thought it was wrong to let the children be photographed and filmed yesterday. But personally I thought it was wonderful – it's a moment they'll remember for the rest of their lives, as will we. I hope the four of them are very happy in their new life together.
