Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, what estimate he has made of the number of electors who were eligible to vote in the 2017 General Election but who did not register to do so.

I refer you to my recent answer to the member for Oldham West and Royton, PQ109192: Information regarding the total number of unregistered people of voting age is not held by the Government. Only totals for the number of registered electors are held, and these can be accessed through the Office for National Statistics website.
