Ed Davey: ‘Tactical voting can lock Tories out of power for a generation’

Lib Dem leader says people lending their votes to rival parties could shut the door on Conservatives at Westminster for years to come

The Tories could be locked out of power for a generation if supporters of other parties vote tactically at the next general election, the Liberal Democrat leader, Ed Davey, says on Sunday, after his party chalked up another stunning West Country byelection victory.

A massive 29% swing to the Lib Dems saw Sarah Dyke take the Somerton and Frome seat, overturning a Conservative majority of more than 19,200. Davey's party now has a comfortable 11,000 majority of its own, the largest it has ever had over the Tories in the constituency.
