I was a member of the Wimbledon congregation for about 8 months and left in June 2013. I never once met or saw this guy and have never heard of him. It says he was a member for 20 years, perhaps, but if he was he was far from regular, or I would know him. I was very surprised when I read this article on my tube ride home in the paper, as I assumed I knew everyone in Wimbledon. Jookbeard, as stated above, was in Wimbledon before me so will be interesting to see if he knows him.
Jonathan Morley, mentioned in the article is the PO or whatever they call that now.
As St. George said, the infamous Michael Porter is in that same Congregation, I knew him well.
