Vote Leave broke electoral law on 4 charges. Note the cynical press release by the BBC, when everyone is celebrating the England win (yes JC, I was waving my England flag) instead of allowing the Electoral Commission to publish their own results. A good day to publish bad news eh?
This should mean the referendum is null and void.

Actually it doesn't make the referendum result null and void. Why ? Because, as remainers take delight in telling us so often, it was an advisory referendum. It was an act of Parliament that activated Article 50 not the referendum.
