Tony Blair has demanded an inquiry into the leaking of Lord Hutton's report on the death of Oxfordshire weapons expert Dr David Kelly.

The Prime Minister was said to be "very angry" about the leak to The Sun newspaper of extracts which cleared the Government but criticised the BBC over the naming of Dr Kelly in press reports.

The Tory party has blamed the Government for the leak but Downing Street has denied it was responsible. Tory leader Michael Howard has called for a full investigation into the leak.

The BBC denied being responsible.

Lord Hutton will set out the key findings of his report in a TV statement at 12.30pm today (January 28), an hour before his report is officially published.

Mr Blair will then answer questions from MP's during a Commons statement at 2.00pm.

Dr Kelly, who lived at Southmoor, near Abingdon, apparently killed himself last July after being named as the source for a BBC report that claimed the Government exaggerated the threat posed by Iraq's claimed weapons of mass destruction.

According to the reports in The Sun, Lord Hutton cites psychiatric evidence that Dr Kelly committed suicide because he had been publicly disgraced.
