Gordon Brown is portrayed here with some degree of admiration, both for what he has achieved as Chancellor since 1997 and for his undoubted and strongly-held ideological underpinnings (one of the many similarities with Thatcher that Peston brings to our attention). This is well-written, highly journalistic book, packed full of detail, anecdote and who allegedly said what to whom, why and when in the corridors of power in Westminster. However, it's not all about recurring personality clashes and murky insider machinations. There are cogent evaluations of Brown's role in Labour Party politics pre-1997, his expansive role in social and economic policy-making as Chancellor, and good summaries of the effectiveness of his flagship policies, plus much that is useful on the changing internal machinery of the Treasury. The fraught and sometimes embittered relations between the Treasury and No. 10 are a recurrent and enjoyable theme here. Peston effectively conveys the importance of certain members of Brown's political clique, espcially Ed Balls, with latter coming across - again, with no little admiration - as the animating genius of much that Brown and the Labour government have done on macro-economic policy since assuming office. The most insightful and interesting pages are reserved for Labour's internal politics surrounding the UK's potential entry to the Euro, which is covered in two excellent chapters; much light is shed on the differences and divisions between Brown and Blair on this issue.
Overall, then, an often fascinating book, both informative and enjoyable - the author has much to say about both the man (Brown) and the machine (the Treasury) that he has dominated for nearly a decade.
