Sets new benchmark for the writing of contemporary political history’ Guardian. With unparalleled access to all key players, this is a story of calculation, attempted coups and people torn between principles and loyalty.

It is a book about our leaders and their closest aides, the decisions they make, how and why they make them and how they feel when they turn out to be so wrong. In All Out War, Tim Shipman has written a political history that reads like a thriller, exploring how and why David Cameron chose to take the biggest political gamble of his life, and why he lost.
