Yes, I heard the sad news yesterday. Gutted. Paul was a superb actor    

My Dad and I are going through the DVD sets of Blake 7. I quite liked Avon's sardonic wit! RIP Paul.

Yes indeed @Welly. His wit, and the banter between him & Vila (played by Michael Keating - who is also superb) create some wonderful moments.
What is so good about Paul Darrow though, was that even Terry Nation said Paul had taken a character who in the scripts, was slightly dull. But Paul made Avon's role so central to the plot.

Paul also managed to be the perfect "anti-hero" - he was the good guy, whilst simultaneously being completely untrustworthy - you knew that all his motivations were completely self-centred.  That's not an easy role to pull off.
