How many prosecutions for failing to complete the registration form for the electoral register there were in 2009.

The Electoral Commission informs me that, in March 2010, it published data based on returns from 351 electoral registration officers showing that, in Great Britain, a total of 67 prosecutions were initiated in relation to a failure to provide information in response to the 2009 annual canvass. The commission does not hold data on the outcomes of those prosecutions. No such prosecutions were initiated in Northern Ireland in the same year.

Why is the Electoral Commission not pressing returning officers to use the law, or does the Electoral Commission regard itself as the arbiter of good and bad electoral law?

The primary responsibility to decide whether to prosecute lies with electoral registration officers, and the hon. Gentleman may want to discuss this issue with the EROs in his community. The Electoral Commission does, of course, issue guidance to EROs and monitors their performance, and it will continue to do so.
