The 2017 general election was supposed to be a walkover for the Conservative Party – but the voters had other ideas.

In The Lost Majority, Lord Ashcroft draws on his unique research to explain why the thumping victory the Tories expected never happened. His findings reveal what real voters made of the campaign, why Britain refused Theresa May's appeal for a clear mandate to negotiate Brexit and where the party now stands after more than a decade of 'modernisation' . And, critically, Ashcroft examines the challenges the Tories face in building a winning coalition when 13 million votes is no longer enough for outright victory.

This is an indispensable guide that will provide food for thought to anyone wishing to examine in detail what really happened on 8 June, 2017, and how this will impact on future elections.
