As David Cameron's director of politics and communications, Craig Oliver was in the room at every key moment during the EU referendum - the biggest political event in the UK since World War II.

Craig Oliver worked with all the players, including David Cameron, George Osbourne, Barack Obama, Angela Merkel, Jeremy Corbyn, Boris Johnson, Michael Gove, Theresa May and Peter Mandelson.

This is raw history at its very best, packed with enthralling detail and colourful anecdotes from behind the closed doors of the campaign that changed British history.
