Home secretary Theresa May makes the case for the government's proposal to impose a minimum price per unit of alcohol:
"Too many people think it's a great night out to get really drunk and have a fight in our streets
"What we need to do is to set a price that is actually going to ensure that we don't damage responsible drinkers.
"People who like a drink or two, who like going down their local pub, have nothing to fear from this policy.
"But what we do want to do is to affect the cheapest end of alcohol, those sorts of offers that enable people to really do this 'pre-loading' - so many people now just get drunk at home before they go out, and that's what causes the problems in our town centres.
"They're the people causing the mayhem."
