The British judge heading the inquiry into the death of Iraq arms expert, Dr David Kelly, has said he would decide what matters would be investigated.
In a statement detailing his terms of reference, Lord Hutton said he would sit mostly in public and report on his findings as soon as possible.
Lord Hutton is expected to look into two crucial points - how Dr Kelly's name was made public, and what exactly he said when he met the BBC journalist Andrew Gilligan to talk about Iraq's weapons of mass destruction.
The inquiry was announced by the British Prime Minister, Tony Blair, following the discovery of Dr Kelly's body near his home in Oxfordshire on Friday.
The BBC has admitted that Dr Kelly was the principal source for a story claiming that Downing Street had exaggerated the threat posed by Iraq's weapons.
Pressure is now mounting on the BBC following the confirmation. There are calls for resignations at the highest level in the organisation.
