I really enjoyed the profile of Ralph Topping in the Sunday Times. Of course, I can’t link to it online because it’s a subscription site, but if you can get hold of a copy, it’s well worth a read. It really brings out his character, and in my view he comes across extremely well.
Still think his opinion of layers on Betfair is baseless, mind. 
Surely the reference to spread betting taking over the world was supposed to be exchanges!
