European Union Bill

This is not the time to talk about changes to the Representation of the People Act 2000, although it is probably the place, but the Minister will be aware of the great concern here and in the country about extending the right to vote to prisoners. My understanding from the ruling of the European Court of Human Rights is that that applies only to general and European Parliament elections, so is it not possible to include in the Bill a specific disfranchisement of prisoners, who otherwise would have an opportunity to vote on constitutional matters?
