It's interesting tha Gordon Brown's book, even after all the publicity of the last few days. has only reached number 367 in the Amazon bestsellers chart. By any normal rights it would be at least in the top 50 by now, if not in the top 10. Tony Blair and Peter Mandelson were both number one bestsellers. OK, this book is not a memoir, but I would have expected it to have reached the top 100. Bear in mind Peter Watt's book got to 52 and both David Laws and Rob Wilson's books got inside the top 200.
I think Simon & Schuster, Gordon Brown's publishers will be a tad disappointed by this performance. I would be if I were them.
