Claudia Winkleman

Simon is set to appear on Radio 2 to promote his new play on Claudia Winkleman's show. That sets Grandma off on a critique of the Winkleman fringe ("Rrrgh, puts me right on edge... How can she see with such a fringe? It's dangerous, tell her.") Still, things are going quite smoothly until Auntie Liz arrives, whereupon Grandma's repertoire of things to offer houseguests at times of tension is put to the test.

This week, there are satsumas, Petit Filous and kitchen hardware ("What about a whisk? I've got two whisks!"). It's a lovely episode, full of painfully well-observed dialogue and cringe-making comic performances. Plus, the news that Clive is unexpectedly keen on Biffy Clyro.

Has Radio 2 missed the style train with its line-up today? Here's a celebrity-based panel show in which comedians and commentators vie to come up with gossipy quips about showbiz personalities.

Somehow all of those ingredients sound a bit past their sell-by date these days. After a decade of chitterchat by so-called entertainers about nonentities, not to mention public enquiries into the dodgy provenance of some of the gossip in the past, it all feels a bit stale. But, who knows?

Maybe Claudia Winkleman, hosting, can raise a little glitter from Andrew Maxwell, Katy Brand and Russell Watson.

Radio 2's Hot Gossip is a panel show hosted by Claudia Winkleman about celebrity tittle-tattle, but not in the shameless we-don't-care-if-you-think-we're-shallow sense. It is, in fact, propelled by shame.

Winkleman's job is to ask questions about the latest goings-on among the rich and famous to a gaggle of publicity-hungry comics who then spew damning one-liners about said celebrities whom they deem to be lower down the food chain than they are. It's less a case of scraping the barrel than tipping it sideways to see what is lurking beneath it. This explains why Winkleman shrieks and whoops at her guests' every utterance as if living in fear that a nanosecond of silence will bring the audience to their senses and prompt a stampede for the exit.

All on the programme seem to think they are above discussing the antics of bed-hopping footballers or reality television alumni, despite the fact that this is exactly what they have signed up for. This week, Jason Byrne was quizzed about a star of the TV series The Only Way Is Essex; he pleaded ignorance both of the show and its well-known acronym TOWIE, which he said he had assumed was "some sort of slang for a tramp". In another instance, Winkleman puzzled over the identity of the former X Factor singer Cher Lloyd. "Wasn't she in the singing thing?" she asked, making out as if she spends her Saturday nights working through her Tarkovsky collection. She wasn't fooling anyone.

Hot Gossip is for people who claim to loathe Hello! magazine, but make weekly dentist appointments so that they can inhale its contents in the waiting room. Why it exists remains a mystery. If the format seems tired, the people who appear on it sound positively knackered, their exhaustion presumably compounded by their round-the-clock schedule of appearances on identikit BBC panel shows.

Acerbic tongues have been licking up the lemon juice in preparation for the return of Claudia Winkleman's deliciously scurrilous take on celebrity life. Joining her to tell us things that are not necessarily true about events that probably did happen are Dom Joly, Nick Hancock and Jo Caulfield. A crack legal team are on standby.

It's rare to find impressionists whose material matches their talent but for most of this enjoyable half-hour programme Jon Culshaw and Debra Stephenson have pulled it off. Both find moments to shine. Culshaw nails fashion consultant Gok Wan's slangy lingo and makes a suitably narcissistic Elton John. Stephenson shows us what it would be like to be stuck in a forest with Kirstie Allsopp and excels with her uncanny take on a breathless squinty-eyed Claudia Winkleman.

The Impressions Show saw Debra Stephenson miss two open goals with Hilary Devey and Tulisa. But with her physique, her Mary Portas, Claudia Winkleman and Fiona Bruce were exactly like the real thing - only foxier.

Jon Culshaw on the other hand was such a car crash his impersonations were more fascinating. His 'Bruce Forsyth' was bang on - if it had been Alex Ferguson, while his 'John Bishop', was the spit of Laurence Llewelyn Bowen. Final score? Debra Stephenson 5 - Jon Culshaw 0.

Jon Culshaw might not be the best mimic to have graced the small screen, but he still knows how to serve up an enjoyable half hour of comedy as his Impressions Show returns for a new series. The real star here though is Culshaw's altogether more impressive co-star Debra Stephenson, whose take on Claudia Winkleman is worth tuning in for alone.

The ubiquitous Claudia Winkleman presents a third episode of King Of, the chat show with a difference. Not a very big difference, but a difference nonetheless. The idea is that the panellists pick who or what is the "king of" various things: the best cheese, the best Chelsea midfielder, the best whatever. Like Room 101, then, but backwards. Today's guests are Lorraine Kelly, daytime TV sofa-dweller, and the comedian Jack Whitehall.
