1/6. A bunch of brave innovators try to persuade five multimillionaires to invest in their ideas, but are they more likely to get a scorching when they pitch their products in the Den? Among the "innovations" under scrutiny tonight are a right-hand glove to aid safe driving abroad, a lemon slicing device for pubs, walk-in stress relief shops, streetwise puppets to teach teenagers and a woollie warmer for new-born lambs.

PICK OF THE DAY DRAGONS' DEN The fire-breathers prepare to reduce more poorly thought-out business plans to toast
REALITY
Dragons' Den 8.00pm BBC2
ITV now has a watery imitation of Dragons' Den where Richard Madeley says things like "Well done, baby" to contestants if they manage to talk a panel of millionaires out of cash. Hard to imagine that kind of language here: as series four of the addictive business show starts, the Dragons are the same grouchy gang of bullies we've grown to love, or at least respect.
Peter Jones still glares at the wannabes who pitch for investment money as if they'd just spat at his mum; Duncan Bannatyne looks like he wants to ask them outside to settle it like men; Deborah Meaden purses her lips like a disappointed schoolmarm; and the Australian one with the floppy fringe tries to keep up. Star of the show, though, is Theo Paphitis: not since Sean Connery has one left eyebrow said so much without words. David Butcher Den of equity: page 14
