Aside from the Torygraph's right wing stance & ownership, it was spoonfed a whole host of anti-Iraq propaganda by friendly spooks.
From George Monbiot on "The Lies of the Press":

By far the worst of these offenders is the Sunday Telegraph. In September 2001, it claimed that ?the Iraqi leader had been providing al-Qaeda ? with funding, logistical back-up and advanced weapons training. His operations reached a ?frantic pace? in the past few months?.(13) In October 2001 it reported that ?Saddam Hussein has relocated his chemical weapons factories after the first case of anthrax poisoning in America ? A senior Western intelligence official said that ? ?The entire contents of their chemicals weapons factories around Baghdad have been moving through the nights to specially built bunkers?.?(14)
In September 2002 it reported that ?Saddam Hussein is developing frightening new ways to deliver his arsenal of chemical and biological weapons, including smallpox and the deadly VX nerve agent.?(15) Another report on the same day claimed that ?Saddam is on the verge of possessing crude nuclear devices that could be ?delivered? using ?unorthodox? means such as on lorries or ships. ... Saddam has the capability to assemble all the components required to make nuclear weapons.?(16) In February 2003, it claimed that ?Iraq?s air force has advanced poison bombs?.(17)
All of these stories ? and many others ? appear to be false. But far from retracting them, it keeps publishing new allegations, which look as dodgy as its pre-war claims. Like the Observer, it appears to have been used by black propagandists in the intelligence services and Iraqi defectors seeking to boost their credentials. Unlike the Observer, it seems happy to be duped.
