For the billionaire set, it is all about their social position and power. They are happy to lose 99% of their fortunes, if it means that those less well off end up losing everything. They will still be well off, but nobody will be able to challenge them socially or move into their neighbourhoods.
Tony Blair is most infamous for expanding the use of postal votes:
1 May 2015: UK Times: Postal vote fraud could cost us key seat, Tories claim
by Faisal Hanif, Dominic Kennedy and John Simpson
Conservatives fear they are going to lose a marginal seat because of a surge of postal voting in an area vulnerable to vote-rigging claims.
Pendle, Lancashire, is one of the seats Labour must take from the Tories to win a majority. The borough is on a blacklist of areas described by the Electoral Commission as having a “greater risk of cases of alleged electoral fraud being reported”.
Tony Blair’s government gave everybody the right to a postal vote but the system is so open to abuse that an investigation by the Council of Europe has declared British elections “childishly simple” to rig...

5 Apr 2005: BBC: Voting scandal mars UK election
By Barnaby Mason
With Britain poised for parliamentary elections next month, a High Court judge has delivered a devastating ruling on the current arrangements for allowing people to vote by post.
He said: “The system is wide open to fraud and any would-be political fraudster knows that.”
Judge Richard Mawrey quashed the results of two local council elections in Birmingham after deciding there had been systematic large-scale vote rigging.
But the implications are wider: it was regarded as a test case for similar complaints in other cities; and record numbers of people have been applying for postal votes in the general election.
He criticised the government’s insistence that the current postal voting system was working.
“Anybody who has sat through the case I have just tried and listened to evidence of electoral fraud that would disgrace a banana republic would find this statement surprising,” he said...
For several weeks, a special election court heard lurid allegations of postal votes being stolen and forged. Six councillors from Tony Blair’s Labour Party denied wrongdoing...
The current problems date from 2001, when the law was changed to make postal voting available to anyone on demand - no reason required.
The government made the change in order to increase turnout at elections, but critics said it was calculated to benefit the Labour Party most.
Since then, there has been an explosive growth in postal voting, especially in inner city areas...
Evidence presented in court indicated it was possible to intercept or forge both the application forms and the postal ballots themselves.
Many ballots had signatures that differed from those on the application.
The forgers were alleged to have applied for postal votes under names taken from the publicly available electoral roll, asking for the ballot papers to be sent to an alternative address or safe house.
The Birmingham Labour leader, Sir Albert Bore, wrote to Mr Blair saying: “At present, in relation to the handling of postal ballot papers, the law is so general that almost anything is legal.”
There is a striking example of that. The ballot papers seized by the police from the warehouse were handed over to election officials, who decided they had no reason to reject them and included them in the count.
The judge commented to the Returning Officer that her function was nil.
“If something seems wrong with the postal ballot papers,” he said, “you have no powers or resources to ferret around to see if the votes are legitimate.”...
