Another half hour of frothy fun with the inimitable Mr Rob Brydon, comprising a naughty natter with South Shields comedian Sarah Millican, who talks about her rise to stardom having only attended a comedy club for the first time aged 29. There's also a lesson in elegance with cross-dressing artist Grayson Perry, and a romantic gesture from musician Newton Faulkner.

Professing to "expose the wrong-headedness of received wisdom and kick back at knee-jerk reactions", Heresy has a rather sober brief for a comedy panel show, which is probably one of the reasons it keeps getting recommissioned by the serious folk at R4. It returns for a seventh series tonight, with host Victoria Coren welcoming comedian Rufus Hound, artist Grayson Perry and political journalist Julia Hartley-Brewer to the studio. They'll be disputing the received wisdom that women look better in men's clothes than vice versa; and that an artist who doesn't make his own work is a fraud.

Interesting to note how Radio 4 handles the debate show: in the blue corner you have the newest contender, David Aaronovitch (Devil's Advocate, Sat 10:15pm) with his serious slant, and in the red, we welcome back Heresy, which is just seriously funny. Victoria Coren takes on such topics as "an artist who doesn't make his own work is a fraud" and "women look better in men's clothes than men do in women's". The three challengers take such received wisdom, mangle it, and see what comes out in the wash. Grayson Perry, the cross-dressing Turner Prize-winning ceramicist, is possibly the best person to argue against both. Also on the new series debut panel is fearless comedian Russell Hound and political journalist Julia Hartley-Brewer. It is not just comedy, it is a poke in the brain and most welcome on this radio at any time. Ding, ding. Round one!

Women have always been under-represented on Have I Got News For You (last weeks appearance by frock-wearing artist Grayson Perry notwithstanding). So its great to see the comedienne and actress, and the tallest woman in comedy, Miranda Hart taking her first spin in the presenters chair.

Already a familiar face from comedies like Angelos, Hyperdrive and playing the cleaning lady in Not Going Out, Miranda is now going to have her very own sitcom based on her Radio 2 series. It will be starting soon on BBC2.

Shes been on Have I Got News For You's panel before, so has no trouble holding her own against captains Ian Hislop and Paul Merton.
