Yesterday, Mr Cameron responded to plans by 10 councils in the North West to create a by-law making it illegal to sell alcohol for less than 50p a unit.
He told the Manchester Evening News: "I think the idea of the councils coming together on this is a good one and we will certainly look at it very sympathetically.
"Where there can be local decisions we are very happy for that to happen. It may be that we need to do something to help deliver the localist answer."
"I think if what you’re trying to do is stop supermarkets from selling 20 tins of Stella for a fiver that’s what we’ve got to go after.
Dave, if you can tell me where I can buy 20 ‘tins’ of Stella for £5, do let me know, before they put a stop to it, because I could make a fucking killing.
