The government wants to change the way we register to vote.
Currently the system relies on one person in a household filling in the registration form indicating who in the home is entitled to vote.
For years there've been concerns about how vulnerable this system is to fraud. Hence the proposed move to individual voter registration - each person in the household will have to complete their own form. The system has operated in Northern Ireland since 2002.
It is proposed now that it will be in operation in England, Wales and Scotland from 2014. But while Labour support the idea in principle, the proposal to include an opt-out from registration is more controversial. There'll be a vote in the Commons on Wednesday.
I've been finding out more from Dr Stuart Wilks-Heeg from Liverpool University
