The "Prince of Darkness" to his enemies, Peter Mandelson is one of the most effective political power brokers ever seen in British politics. He is widely credited with having masterminded the renaissance of the Labour Party and bringing about their return to power. This biography examines the paradox of the pioneer of modern political campaigning techniques, famously supposed to have said of the 1987 election that "the packaging was great, it was just that the product kept seeping though", who is also steeped in the traditions of the party, grandson of the great Herbert Morrison, and an assiduous constituency MP.
