Are Lorna Watson and Ingrid Oliver poised to become the next French and Saunders?

They've got the talent and are both immensely likeable, but what they're lacking right now is better material.

There's nothing in the first outing for their new sketch show to dislike, but nothing that really stakes out new comedy ground for female comedians in the way that Smack The Pony or Catherine Tate did. A take-off of Kate and Wills capitalises on Ingrid Oliver's passing resemblance to Kate, but doesn't really know where it's going.

What's most worrying is that they deliberately let their guest star John Barrowman steal all their laughs as well.

Eric and Ernie might have used stage stars to their ­advantage, but Watson and Oliver are a long way from being Morecambe and Wise.

We're not writing them off yet - we're just saying they should write off their writers and get some new ones.

Heralded as heirs to the long-vacant throne of French and Saunders, double act Ingrid Oliver and Lorna Watson don't disappoint in this hugely enjoyable new sketch show. With a comedy style that is, in Oliver's words, "big and silly", this pair make an instant splash with impersonations of everyone from the Duke and Duchess of Cambridge to Myleene Klass, period drama spoofs, and verbally dexterous sketches reminiscent of The Two Ronnies. It has a rare sense of comic mischief that teases but doesn't offend.

Cavity was glitteringly original. Sean Grundy's play was a comedy about adultery, fast, sexy and I'd have said 'edgy' too, if that word hadn't recently been bled of meaning. Here, I intend it to convey going as close as possible to the borders of descriptive propriety while employing sharp wit to induce a slightly shocked delight. Alison Crawford directed a marvellous cast - Julian Rhind-Tutt, Ingrid Oliver and Kerry Godliman - with glorious assurance. Afternoon Play is not often as utterly entertaining as this. Everyone, me included, usually moans about it. Frequently, these days, we must admit we can be wrong. If you missed Cavity, you missed a treat.

Sharp, sexy, surreal yet somehow utterly believable comedy by Sean Grundy. Adrian (Julian Rhind-Tutt) starts an office romance with Kirsty (Ingrid Oliver). He takes her home, thinking his wife, Lucy (Kerry Godliman), is away. But she comes back unexpectedly. Kirsty hides, falls into the cavity wall. One thing leads to another, and she stays. And stays. This brilliantly observed piece is not for those who shy at on-air sex. But for anyone who relishes characters who come to life in a situation which grows around them almost magically, don't miss it.

For this particular instalment, Jones found himself casing the catwalk as a professional photographer at a Milan fashion shoot. Despite being pretty lousy at the job - his only relevant experience was taking pictures of animals - he still ended up jetting off to South America to snap an eccentric and often angry Miss Venezuela.

To attempt to explain what happened next would be far too ambitious, let's just say that Jones' adventure featured encounters with Big Foot and a tribe of eco terrorists, and that was after he discovered what going for a Brazilian really meant.

The joy of the programme was in the writing, particularly the running gags, and the way it was performed by Jones and the cast, which included Tom Goodman-Hill, Dan Tetsell, Ingrid Oliver and Ben Willbond.

The second series of this spoof documentary charting the history of that prestigious 19th Century family the Favershams is amusing and witty, with the odd laugh-out-loud moment thrown in for good measure.

Four sons of Sir Digby and Lady Alexandra Faversham were featured previously. This time the first of four instalments placed the spotlight on Titus Faversham (known to his friends as TC), son number five and Victorian Britain's greatest sportsman.

The writing of this tale really came into its own as TC became such an accomplished athlete at school that he simply leapt from one team to another, whether it be polo, cricket, football etc - he even beat a dolphin at swimming. But as his teammates were persuaded to turn pro and get paid for their sporting prowess, TC was determined to stay a gentleman amateur, however poverty stricken it made him.

Soon he discovered that one nasty entrepreneur in the new world was not just scheming to overthrow the mighty England at sport but was taking a stab at the Empire as well. Surely TC had to step in and save the day.

Humphrey Ker, David Reed and Thom Tuck (The Penny Dreadfuls) provided some of the best radio comedy writing and wordplay I had heard in a long while, boosted by great performances from other cast members Ingrid Oliver and Miles Jupp. Interestingly the producer was Julia McKenzie, an actress who, in her own right, has performed everything from satire to sitcom. Her experience in the genre must have been a bonus.
