CAMP Sean Tully spends his working days with his hands in women's knickers as one of Underworld's hardest workers in Coronation Street (ITV1).

Away from the underwear factory, he likes nothing better than rummaging about in a pair of boxers (and it doesn't matter whether they're world champions).

Now he has other things on his mind. He's in the middle of a troublesome threesome. He's rekindled the fire with old flame Sonny-Side-Up, the bisexual businessman who's going out with Michelle, who works alongside Sean behind the bar in the Rovers.

Soapland hasn't seen anything like it since Ena Sharples appeared without her hairnet. Spotting Sonny-Side-Up and Camp Sean locking lips caused Steve McDonald's already upwardly mobile eyebrows to take on the appearance of demented caterpillars. Soon Steve, who fancies Michelle, begins dropping hints that Sonny-Side-Up has a foot in both camps.

This causes Michelle's brothers Liam and Paul to take Sean aside for a quiet word - words actually, "tell the truth or you'll be force fed Betty's hotpot". Sean fesses up, gets a slap from Michelle and is driven straight back into the arms of Sonny Side Up.

In another dark corner of The Street, Terrible Tracy and Demonic David, Weatherfield's answer to Pinky and Perky, are getting their story straight before she goes on trial for murdering Charlie the builder with the big toolbox.

David's going to be the star defence witness, provided she pays him for his services with sex. We know Tracy will stoop to anything, like a dog owner with a poop scoop, to get out of jail free but bedding David is bad even by her low standards.

Little does she know that Jason Grimshaw has witnessed their touchy-feely session on CCTV. He thought he was tuned into the Weatherfield Readers' Wives channel but instead sees Tracy stroking David's cheek (face, not bum). It says here that Jason puts two and two together which means their secret is safe because he's not the sharpest chisel in the toolbox and maths isn't his strong subject.

DCI Grace Barraclough is like a mountie. No, she doesn't wear a big hat and silly trousers, she always get her man. Or, as we see in Emmerdale (ITV1), her men. She arrests the Three Stooges - the King brothers - for the murder of their father Tom, the king of Kings. Her ploy seems to be to arrest everyone in the village one-by-one in the hope that at some point she'll nab the guilty party. Getting bored, like the rest of us, with locking up a fresh suspect every week, she decides to speed things up by handcuffing three at once.

She should really be arresting Eric Pollard's son David (why are people called David so sneaky in soaps?). He's a real chip off the old crooked block as he's been stealing from his father. Del realises what's happening but opts to keep quiet for fear of losing the man she loves.

The Rob/May/Dawn triangle continues to causes problems in EastEnders (BBC1). Rob and Dr May, the worst GP in the world, want to keep the baby that Dawn is having after sleeping with Rob. Dr May's ante-natal advice is to tell Dawn to sleep regularly with her husband, not perhaps what the doctor should be ordering. Kevin Wicks reappears in Walford, prompted by witnessing something nasty. Not Big Pat without her make-up but a road accident. Shirley, his ex-partner and the mother of the children that have turned out not to be his, does the decent thing and comforts shocked Kevin. Or rather, she does the indecent thing and sleeps with him.
