Is potting shed pinup Monty a plant on Question Time panel?

Not to be outdone by Sky News – it has an all-women lineup today for International Women's Day – the BBC will be broadcasting its own range of programmes this week to mark the day that "celebrates the economic, political and social achievements of women". The programmes include Thursday's Question Time, which will "for the first time ever feature an all-women audience" adding, somewhat unnecessarily, "a panel including the broadcaster Monty Don ". Are the two, in any way, related?
