Looks like it may be a D notice. The details are possibly that Porton
Down scientists cannot be named. That would affect the following lines.
A few days later in the lab, Dr Martin Pearce, head of the Biological
Weapons Identification Group, found that there was no ricin.
Nevertheless, claimed Porton Down chemistry chief Dr Chris Timperley,
they showed a "common origin and progression" in the methods, thus
linking the London group of north Africans to Afghanistan and Bin Laden.
The weakness of Timperley's case was that neither he nor the
intelligence services had examined any other documents that could have
been the source.
The article may well re-appear with the above removed.
