gemporia replied to post on their fb page saying this:
peter Simon joined us on a short term basis.he no longer works for gems tv but we wish him the best of luck with his future endeavors,thank you gemporia.
wondering here but couldn't they have put him onto one of their other shows,given him a co presenter to help him if he struggled..wean him in that way for a few months to get him to thungs,then he could do a full show on gems?
