A man whose lies helped to make the case for invading Iraq - starting a nine-year war costing more than 100,000 lives and hundreds of billions of pounds - will come clean in his first British television interview tomorrow [click here for interview]. "Curveball", the Iraqi defector who fabricated claims about Iraq's weapons of mass destruction, smiles as he confirms how he made the whole thing up. It was a confidence trick that changed the course of history, with Rafid Ahmed Alwan al-Janabi's lies used to justify the Iraq war. The chemical engineer claimed to have overseen the building of a mobile biological laboratory when he sought political asylum in Germany in 1999. His lies were presented as "facts and conclusions based on solid intelligence" by Colin Powell, US Secretary of State, when making the case for war at the UN Security Council in February 2003. But Mr Janabi ... says none of it was true. US officials "sexed up" Mr Janabi's drawings of mobile biological weapons labs to make them more presentable, admits Colonel Lawrence Wilkerson, General Powell's former chief of staff. "I brought the White House team in to do the graphics," he says, adding how "intelligence was being worked to fit around the policy". Another revelation ... is the real reason why the FBI swooped on Russian spy Anna Chapman in 2010. Top officials feared the glamorous Russian agent wanted to seduce one of US President Barack Obama's inner circle. The fear that Chapman would compromise a senior US official in a "honey trap" was a key reason for the arrest and deportation of the Russian spy ring of 10 people.
