The news that Sarah Green has wrested the constituency of Chesham and Amersham off the Conservatives for the first time in its history merits a look back over the Liberal Democrat's long decline. The centre ground is not an easy place to be in politics, and the new MP has needed the frequent sight of HS2 bulldozers and stormtroopers to get her majority - but she's done it. This look-back over Liberal Democrat history with Simon Rose and Mike Indian was first published in October 2019, just before the last General Election.
