The Prime Minister said Britain should be able to decide whether its tens of thousands of prisoners vote, rather than a “foreign court”.
He backed MPs for last year deciding to keep the 140-year-old ban on prisoner voting, even though the European Court of Human Rights (ECHR) has ruled that this must be changed.
At Prime Minister’s Questions, he said: “I have always believed when you are sent to prison you lose certain rights and one of those rights is the right to vote.
“Crucially, I believe this should be a matter for Parliament to decide, not a foreign court.
“Parliament has made its decision and I completely agree with it.”
