How many actions do the police or the DVLA make against misrepresented licence plates?

[UPDATE: ] a FOI request has produced this information:

Of the 22 marks withdrawn by the Agency, 18 misrepresented registration marks were withdrawn as a result of police notifications, and 1 withdrawn as the result of a notification from a DVLA enforcement officer."
