If you have not received your ballot yet and your details have not changed, request a reissue by:
1) visiting www.labour.org.uk/re-issue and filling in your details, or
2) call the party on 0345 092 22 99, phone lines are open Monday to Friday 9am-5pm.
You need to do this well before Sunday 11 September (as a new ballot will typically take 10 days to arrive).
