when was the prevent strategy introduced by the labour government?

The Prevent strategy was introduced by the Labour government in 2003 as part of the UK's counter-terrorism approach following the 9/11 attacks. It was designed to prevent people from becoming terrorists or supporting terrorism and was particularly emphasized after the 7/7 London attacks in 2005. The strategy was later revised by the Coalition government in 2011 and again by the Conservative government in subsequent years.
