Electoral probity, universal suffrage and the secret ballot are the three keystones of a stable democracy. Labour, in an astonishing display of party interest above national interest, support the corruption of all three legs of our democratic stool in ways that unfairly favour Labour.
Electoral probity is only gradually being restored after long neglect by all parties and determined efforts by Blair / Brown to undermine the democratic process. As Michaeel Pinto-Dischinsky commented, we have 3m on the electoral roll who shouldn't be and we had 3m missing who should be. Individual voter registration is weeding out the double and false registrations, and the recent referendum has brought in 2m of the missing 3m. Good enough.
Second, we have an Electoral Quotient that is way beyond the basic +/- 5% envelope required for a fair electoral system, and in comparison to the +/- 3% achieved by advanced democracies such as New Zealand it makes the UK literally third-world in EQ standards. This necessary change needs no debate, and the pained whine coming from Labour at the prospects of losing more underpopulated seats than the Tories is simply contemptible.
The fair issue for debate is what the EQ should be - and how many MPs the Commons should have. My own view is that Cameron's proposed reduction to 600 giving an EQ of 71,031-78,507 voters per seat is about right - given that the long-term trend is for devolution, localism and a reduction in the scope of the national Parliament to matters of national importance. As devolution gathers pace, this number should be reviewed and may need to fall further.
Labour's point that the proposals are based on the 2015 electoral registers, disregarding the 2m new registrations this year, are short-sighted, and Theresa May could make things even more painful for Labour by including them. The new 2m are largely in constituencies in cities and urban SE areas and will only lose Labour more seats in the de-populated outer zones. The 2015 election was based on electoral lists that included 7m suspect registrations - which were due to be removed by 2016*, losing up to 10% of electors in some Labour inner-city constituencies. So by all means base the EQ on the very latest electoral lists available - Labour will only suffer more. The population drift from Wales, the NE and other stagnant areas of the UK to London and the South-East - from traditional Labour areas to Tory areas - is continuing and will continue.
Labour's whining about changes that strengthen and regulate Britain's democratic systems simply shows that the party is acting now wholly in its own interest and with no regard to the good of the British people.
* But evidently weren't - Voter figures are 46.4m in 2012, 44.7m in Dec 2015 and 46.5m for the referendum. We must await the Boundary Commission report for greater clarity.
