Is it just me or does Head of Brand Siobhan Sharpe (Jessica Hynes) remind you of Natasha from The Apprentice?

I'm not quite sure if it's her sideways hairdo or that utter blankness behind the eyes as though her brain and her mouth aren't quite hooked up.

Either way, she's my favourite character in this comedy of cock-ups and her quest to find a "sonic brand" for the Olympics this week is another classic moment for her.

But the really big drama comes from the discovery of some ancient bones under the planned site. Or, in the words of narrator David Tennant: "The Aquatic Centre has suddenly gone from being this week's good news story to a mass grave..."

Personally, if I were Head of Deliverance Ian Fletcher (Hugh Bonneville) I'd be more concerned that my Chief Construction Engineer is actually Mr Masood the postman from EastEnders.

The BBC4 comedy makes the move to BBC2. There will come a time soon, after the cost is tallied and the results examined, when the 2012 London Olympics will be no laughing matter. Until then, it's fair game. Writer-director John Morton previously helmed the great People Like Us, and here the tone is similar and the standard just as high. Set in the Olympic Delivery Committee, complete with dreadful logo, we meet the excellent cast - Hugh Bonneville, Olivia Coleman, Jessica Hynes, Vincent Franklin - as they prepare to relaunch their website. A terrific start.

True Olympic buffs won't be able to hear the theme music for this sitcom - Let's Face The Music And Dance - without thinking of Torvill and Dean having to settle for bronze in Lillehammer in 1994.

There's no such fancy footwork here in a series which makes you wonder what percentage of the energy that goes into hosting the Olympics has anything to do with sport itself. This week's debacle concerns a former Olympian called Dave Welbeck (a glorious turn from guest star Darren Boyd).

Dave has been roped in as the figurehead of an inspirational initiative called Raising The Bar, but his presentations to schoolchildren are so bafflingly inept, they're almost an art form in themselves.

All of which presents a major hurdle for the harassed Head Of Brand Siobhan Sharpe (Jessica Hynes) who has a wonderful way of seeming to talk through her eyelids.

Meanwhile, Kay's proposed wind turbine - aka The Angel Of Leyton - which is supposed to be symbolising their commitment to green issues has hit a brick wall.

Siobhan and Ian have another pointless meeting. Jessica Hynes really nails dead-eyed ennui as the half-wit PR consultant and Hugh Bonneville is perfectly pitched as the pleasant but ineffectual executive. And tonight, the superb Darren Boyd plays ex-athlete Dave Wellbeck, now an "Official 2012 Hero" charged with inspiring the nation's youth about sport. Olivia Colman continues to be consummately understated as Ian's PA, Sally. The writing is up there with Morton's other wondrous work, People Like Us, and wholly deserves primetime BBC2, not this hidden nook on digital. Perfection.

This pitch-perfect mockumentary starring Hugh Bonneville and Jessica Hynes is proving unerringly close to the mark. In this third episode the Olympic Deliverance team learns that Roman remains have been found beneath the site of the aquatics centre forcing the team to make last-minute modifications to the building. Will it matter if athletes have to go through the canteen to get from the changing rooms to the pool?

Hugh Bonneville is in charge of Twenty Twelve, Sophie from Peep Show plays his secretary and Alan Partridge's Polish wife is on the organising team along with The Thick of It and Green Wing dependables.

As with People Like Us but not The Office, it's fairly gentle. There are frustrations and thwartings but no one is a monster.

It's not the last word in biting satire, possibly because the national mood re the Games is positive, but it's good to have the show out there, well before the first shot from a starter's pistol.

Actually, if not quite a monster, there is one member of the team who is monstrously idiotic and who will bring smirks of recognition to every journalist who's ever had dealings with a PR ninny (and that, by the way, is all hacks).

Jessica Hynes as Siobhan Sharpe says things like "Matthew Pinsent? I don't even know who he is" and "So this Hoy guy, the one with the huge legs yah?" and "She's terrific in the water but out of it she's got this big nose thing going on". You'd have to say Sharpe is positively Olympian in her berkishness.

As the Olympic clock tick tocks its way down to the big event, this new comedy couldn't be more timely. This six partner stars Jessica Hynes, Hugh Bonneville, Amelia Bullmore and Olivia Colman who form the team who have to troubleshoot their way to the opening ceremony. Some of the challenges they face may seem utterly unconnected to watching Sir Chris Hoy bombing round on his fancy BMX, but if there isn't enough wind to move the wind turbines or properly phased traffic lights, the whole event would be a disaster. Written by and directed by People Like Us writer John Morton, we expect it may not be as traumatic as the real Olympics in a year's time.

When London's countdown clock to the Olympics ­malfunctioned last week, it was an uncanny rerun of the first episode of this cruelly observed docu-spoof.

The second episode finds London's Olympic Deliverance committee stuck on a bus with a delegation from Brazil and things are still refusing to run like clockwork. They're heading for a meeting with Sebastian Coe at the Olympic Park - or then again, possibly not, thanks to the wonders of satnav and bus drivers with only the vaguest grasp of London geography.

Leading a brilliant cast is Hugh Bonneville as the ­ultra-calm Head Of ­Deliverance - a master at "managing expectations" and staying positive at all costs.

We're also loving Amelia Bullmore (Head of ­Sustainability), waffling ­meaninglessly about how "Sustainability is not legacy", as well as Jessica Hynes]s shinily robotic Head of Brand and Karl Theobald's panic-stricken Head of Infrastructure.

The narration by David Tennant is as warmly soothing as a foot rub and the job titles alone are enough to make you smile.

The only downside in this perfect comedy of cock-ups is the BBC has been accused of ripping off 1998 Australian ­mockumentary The Games, about inept officials ­planning for the Sydney Games.

The BBC strenuously denies it, but the producers of The Games claim to have had talks with the BBC's head of comedy about a British equivalent, and actually loaned the writer of this one a DVD of their own show. So has the Beeb been a very bad sport?

Video: Olympics used for new comedy

Actress Jessica Hynes stars in a new comedy about a PR team trying to sell the Olympics to the public. The show, called Twenty Twelve sees Hynes play Siobhan Sharpe, an efficient yet slightly clueless PR manager.

Jessica spoke to BBC Breakfast about the series and why the Olympics is a good backdrop to write a comedy.

Stick the fantastically funny spoof documentary Twenty Twelve on BBC1 or BBC2 and we'd have a guaranteed smash hit on our hands. So what do they do? Relegate it to the ratings wasteland of BBC4. ­

Starring dazzling duo Hugh Bonneville and Jessica Hynes, this ­hilarious Olympic farce is must-see TV.
