Question to the Cabinet Office:

To ask Her Majesty’s Government what is their assessment of the accuracy and completeness of the United Kingdom electoral register.

On 18 June the Electoral Commission published their analysis of the state of the electoral registers in Great Britain used for the General Election. The data collected for the report did not allow an estimate of the completeness and accuracy to be made.

The last full assessment of the completeness and accuracy of electoral registers in Great Britain was published in July 2014 and was based on the last household registers prior to the introduction of Individual Electoral Registration (IER).

The next full assessment will be based on the first full IER registers once the transition has ended.

To ensure electors can have confidence in the accuracy and integrity of the electoral register, under IER applicants are asked to provide their National Insurance number and date of birth (or supporting documentation), so that Electoral Registration Officers (EROs) can verify that everyone on the register is who they say they are.
