The judge in the Birmingham vote-rigging trial may have condemned the postal voting system as "an open invitation to fraud" but record numbers of electors are applying for postal votes for the General Election.
A survey by The Guardian newspaper of 55 councils covering 135 constituencies found applications to vote by post had risen in all cases, and even tripled in some areas including Birmingham.
The increase comes as demand grows for urgent changes in the postal voting system to counter fears of fraud.
A report by MPs last week said that as postal voting becomes more common, there is a "strong case" to tighten protection against fraud by requiring voters to register themselves individually, rather than collectively as a household.
The report came just days after Judge Richard Mawrey QC, presiding over hearings into allegations of widespread postal voting forgery in the local elections in Birmingham last June, concluded: " Someone who was so inclined could defraud the system."
The survey found that increases in applications to vote by post are the highest in areas where allegations of postal-voting fraud have previously been made.
In Birmingham's 11 constituencies, more than 53,000 people have asked to vote by post, compared with 16,000 at the last election.
In Woking, where police are investigating allegations of postal-voting fraud during June's local elections, 15,000 electors want to vote by post compared with 2,356 last time.
The Electoral Commission has recommended that postal voting should remain part of the voting process but the process needs to be tightened.
The Tories claimed last week that postal voting was in danger of bringing about a return to "18th Century fraud".
Shadow leader Oliver Heald argued that there were various problems with postal voting, telling MPs he had previously "cited examples of babies receiving ballot papers, heads of families filling them in for the whole family, employers threatening to sack staff unless they voted for a particular political party, and other worrying abuses".
The Birmingham case has centred on allegations, outlined in two election petitions, that six Labour councillors were elected in the Bordesley Green and Aston wards after masterminding the fiddling of postal votes on an "industrial scale".
The number of postal votes issued in the 2004 elections in Birmingham went up from 24,000 the previous year to 70,000. There were 7,000 postal votes in Bordesley Green alone - five times as many as votes cast at polling stations.
The hearings finished last week with Mr Mawrey, a Deputy High Court judge who sat as the elections commissioner, reserving judgment until next Monday - the day Tony Blair is expected to announce the date of the General Election.
