I am satisfied that we have evidence that justifies taking the case forward. I say that not because I have seen the evidence but because three successive Lords Advocate have examined it. They are all leading lawyers and they are all satisfied that there is evidence that justifies us in pursuing the case. The hon. Gentleman has no reason to criticise that approach.

On his fourth question, it is true that Mr. Thurman has been transferred—not suspended—but the case against the Libyans does not depend on any evidence that he might give. Forensic analysis was also done at the Royal Armament Research and Development Establishment. Professor Caddy made it clear that the evidence in that case and others was a true measure of the presence of the explosive RDX.
