Lib Dems rule out tactical voting pact with Labour in byelections

Leader Ed Davey says party will fight for both seats after resignations of Boris Johnson and Nadine Dorries

Sir Ed Davey, the leader of the Liberal Democrats, has ruled out a formal pact with Labour to encourage tactical voting in order to beat the Conservatives in the byelections triggered by Boris Johnson and Nadine Dorries' shock resignations.

Dorries, one of Johnson's fiercest cheerleaders, quit parliament on Friday after being told she would not be elevated to the House of Lords in Johnson's resignation honours list. Johnson followed suit hours later, ditching his outer-London seat with a bitter resignation statement accusing Rishi Sunak of leading a government that is not properly Conservative" and attacking the Partygate investigation.
