Question to the Home Office:
To ask Her Majesty's Government how many (1) 18–19 year olds, (2) 20–29 year olds, (3) 30–39 year olds, (4) 40–49 year olds, (5) 50–59 year olds, (6) 60–69 year olds, (7) 70–79 year olds, (8) 80–89 year olds, and (9) 90+ year olds, they estimate to hold an expired British passport.
Data cannot be provided in accurate volumes. This is due to exceptions, including where a passport has not been automatically cancelled on renewal, and where a passport holder is deceased, and their passport record has not been updated.
