How do you protect postal voting from fraud?
When voting by post, you should mark your vote on the ballot paper in secret, and seal the envelope yourself.
You will be asked to give your date of birth and signature when applying for a postal or proxy vote. When you return your postal voting pack you will again be asked for your signature and date of birth, and these will be checked against those you have already provided in order to confirm your identity.
Your signature and date of birth are separated from your ballot paper before it is looked at or counted, so giving this information will not affect the secrecy of your vote.
