Can't agree with you about Peter Simon, I thought he was bl%%dy awful, no knowledge whatsoever, just reciting meaningless platitudes, all combined with 'ham' acting and using the presenter he was taking over from as his stooge. The channel must have been inundated with complaints, because apart from a recent presenter who lasted all of 5 minutes he was the quickest presenter to depart that I can remember - accompanied by the 'story' that he was only there on a temporary basis, anyway. Yeah. Right. Of course.
I'd say there was nothing much to choose from between Lyndsey and Peter Simon in presenting capabilities (or lack of), but at least she doesn't try to humiliate the outgoing presenter when she takes over.
