Very interesting.
This was the guy who Hicks brought to the Arsenal game iirc and has been advising on financing matters.
The comment "will represent the owners and oversee all financial and operational aspects of the Club" is the nub of this one.
I'd say the odds of the club being sold have reduced somewhat.
EDIT: actually, I'm going to qualify that - if G&H wanted to sell the club (or part of it), then putting someone like this into the club to tidy it up would be entirely logical, especially given his background. This guy, I guess, is the replacement for Foster Gillett, with the difference being that Purslow is actually qualified for the job. The plot, it seems, thickens.
