Bush book defends waterboarding

George Bush, the former US president, has reopened the debate on the legality of the use of torture in his newly published book Decision Points, in which he defends his "war on terror" in Afghanistan and the decision to invade Iraq.

Bush says interrogation techniques like waterboarding have helped save lives in the US and UK by exposing leading members of al-Qaeda.

In response, the British government, a key US ally in the wars, has reinforced its position against any form or use of torture.
