The publishing sensation of the decade, I think we can all agree:

It is perhaps the most famous address in the world and now Sarah Brown, wife of the former prime minister, is to pen a book about life at 10 Downing Street.

Of course, there is something inevitable about Mrs Brown writing a memoir - no doubt her husband will at some point put pen to paper to write a tedious tome justifying his execrable tenure in Number 10. After all, once someone leaves politics, the autobiography becomes a nice little earner that can help to take the edge off defeat and the loss of a hefty income.

I just hope that Sarah Brown got the right price in order to write this book. At that price, in case anyone was wondering, should have been £2.50 and a can of Vimto.
