Liberal Democrats candidate Sarah Green has snatched Chesham and Amersham from the Tories in a historic win at the by-election. 

In a shock - but resounding - triumph, the Liberal Democrats took a staggering 21,517 votes. 

The Conservatives' candidate Peter Fleet took 13,489, giving Ms Green a majority of over 8,000 votes - a humiliating defeat for the Tories.
