Personally I think people in public life have to fall on their swords if they contravene regulations - setting an example, and all that - and that was the issue with Cummings, he didn't! In this instance he's quit, and that's the end of it. Seems a very minor transgression, and out of stupidity rather than anything else (and I also think Reeves had to phone the police as, imagine the likes of Les Reid with a story if it came out he'd broken the rules and Reeves knew, and did nothing) but he's suffering the consequences, and that's the end of it.
