Who is Mark - the RUK pundit

First appeared for the US racing. Think he works for Timeform, US section?

In fact, if memory serves, wasn't he the one who use to e-mail in a lot when Willo and McNae were doing the US racing back in the day, long before he got the TV gig?

Just about the best pundit on RUK imo

but no end product, very rare. Like that wimp that is on with him.
