The government is expected to unveil a raft of measures to tackle teenage drinking in England later today.

The plans include a 'two-strikes' rule on selling alcohol to children, and challenging anyone who looks under 21 trying to buy alcohol.

Teenagers who are consistently caught with alcohol in public will be given Asbos and acceptable behaviour contracts and parents will also be given advice on safe drinking levels for teenagers.

A "culture change about drinking" was needed, said children's secretary Ed Balls.

"We need to fundamentally influence young people's behaviour and attitudes towards alcohol,” he said.

"This will involve talking to young people themselves but, crucially, parents tell us they want better, clearer information as they bring up their children."
