When do children become criminally responsible?

Following a series of high-profile cases involving young defendents, the question of the age of criminal responsibility in the UK has been raised.

Some child experts argue that children who commit offences needed to be treated differently from adult criminals.

In March, the UK government rejected plans to raise the age in England and Wales from 10, one of the youngest in Europe. In Scotland there are plans to raise the age from eight to 12.
