Britain's teenagers are among the most badly behaved in Europe, a study by a think-tank has suggested.
On every indicator of bad behaviour-drugs, drink, violence, promiscuity-the UK was at or near the top, said the Institute for Public Policy Research.
The institute looked at the results of a number of studies of adolescents conducted in recent years.
The researchers believe the country's record can be explained by a collapse in family and community life in the UK.
