Henry Porter explains how individual liberties have been eroded since Tony Blair became prime minister.

"Identity cards. Number-plate surveillance. CCTV. Control orders. The list of ways in which the Government has sought to manipulate and define the limits of our liberty grows ever longer. Ten years ago, the novelist and polemicist Henry Porter would have felt silly speaking out about human rights in Britain. But that was before the most fundamental assault on personal freedom ever undertaken. Now, he argues, it's time we woke up to reality."
