Electoral Commision annouce there are 7.5m people missing off the electoral register

I received this letter from my colleague Chris Ruane which he has asked MP's to circulate more widely. It was my question on the floor of the House of Commons on 18 June 2012 which revealed for the first time that the government accepted a figure them of 6 million unregistered voters.

The Electoral Commissions announcement today is that there are 7.5m people missing off the electoral register.
