Labour has manipulated Britain's voting system for its own political advantage, Michael Howard claimed today.
The Tory leader said Labour had " manipulated the constitution for partisan reasons".
His comments to The Birmingham Post followed the city's postal voting scandal which led to a judge overturning local election results in two Birmingham council wards.
Judge Richard Mawrey QC found six Labour councillors in Aston and Bordesley Green guilty of trying to rig the 2004 city council elections.
Mr Howard was speaking in response to The Post's Manifesto for the Midlands campaign, in which we challenged the parties to explain what they would do for the region.
He pledged to tighten election laws to prevent a similar scandal.
He said: "Labour have fiddled with the electoral system, ignored cross- party warnings, and damaged the reputation of Britain's electoral system."
Mr Howard also stressed the need to carry out a full investigation into MG Rover.
