Just a bit of forewarning about Radio 4's "Any Questions" (Friday 16.04 20:00, repeated Saturday at 13:15, followed by "Any Answers" phone-in)
"Jonathan Dimbleby chairs the live debate from Woldingham in Surrey with questions from the audience for the panel including: Michael Gove MP, Shadow Education Secretary; Hilary Benn, Secretary of State for Environment, Food and Rural Affairs and Justine Roberts, founder of Mumsnet."
I somehow assumed they didn't want to have politicians (as others who were standing against them could be disadvantaged, unless all of them are standing down).
