Recall of MPs Bill

The hon. Gentleman will correct me if I am wrong, but in Northern Ireland, I think, voters must show ID. In the UK they do not. What is there to stop someone putting someone else’s name on a petition? If the list of names and addresses is not made public, how could anyone challenge an entry and say, “I didn’t sign that petition”? That is a weakness. Even if, in the UK, a presiding officer is present, there is no guarantee of the identity of the person signing.
