Weapons expert Dr David Kelly did believe the British government exaggerated the threat posed by Iraq to support its case for war, according to a BBC journalist. A war of words erupted in May between the corporation and Downing Street after Andrew Gilligan filed a report claiming the government had "sexed up" a dossier on Iraq's weapons of mass destruction. He has been testifying before an inquiry into the death of Dr Kelly who apparently killed himself shortly after being identified as the source of the controversial report. According to the journalist, Dr Kelly blamed the Prime minister's communications chief, Alastair Campbell, for altering the intelligence information. In particular, Kelly accused Campbell of adding a claim that Iraq could deploy chemical or biological weapons at 45 minutes' notice. Testifying before the inquiry on Monday, a Ministry of Defence official said several of his colleagues were unhappy with the dossier which they said did not reflect their views. Dr Kelly was found dead in woods near his Oxfordshire home last month just days after appearing before a parliamentary committee investigating whether the government had indeed exaggerated the threat posed by Saddam. The former United Nations weapons inspector has been described by colleagues as an expert of very high standing, recognised internationally. No weapons have yet been found in Iraq, nearly four months after the end of the conflict, undermining trust in Tony Blair. It is the biggest crisis his government has faced since coming to power six years ago, and could play a key role in the next general election in 2006. **PHOTO CAPTION*** BBC journalist Andrew Gilligan, (Stephen Hird/Reuters)
