I've heard many say that they will not make any report until Blair (and of course his Catholic wife) are out of 10 Downing Street.
http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2007/01/20/nbloody20.xml In January 1998, Tony Blair announced an "urgent" new inquiry and Lord Saville, a recently-appointed law lord with what looked like a promising career ahead of him in Britain's highest court, agreed to take it on.
He finished taking evidence from all but a handful of witnesses in February 2004 and heard closing speeches in November of that year. He made it clear at the time that he planned to submit his report to the Government in the summer of 2005.
But the report is still being written and it is not likely to be ready before 2008.
......
Lord Saville and the two retired Commonwealth judges sitting with him "consider it most unlikely that they will complete the report before the end of 2007 at the earliest, and they may need a longer time even than that".
