It's no longer necessary to cross the Channel to stock up on cheap booze; the local superstore is now the place to head with multipack deals that can work out at less than 70p for a pint of lager.
Whether it's vodka, beer or cider, cheap alcohol is changing the way a generation drink. Rather than head to the pub, 'pre-loading' or 'pre-drinking' is now the favourite way for young drinkers to start a night out.

Antony Barnett criss-crosses Britain, examining how the nation's drinking habits may have changed. He looks at the true cost of cheap alcohol and investigates how the drinks industry have mobilised to fight off government attempts to clamp down on cheap drink.
