The BBC defended its children's show Dick And Dom In Da Bungalow today after it was criticised in Parliament by senior Conservative MP Peter Luff, who condemned the programme's "lavatorial" content.

Mr Luff, an assistant chief whip and MP for Mid Worcestershire, asked how the show, presented by Dominic Wood and Richard McCourt, enhanced the corporation's public service remit.

He invited Tessa Jowell, the Culture Secretary, to visit the show's website. "You can join me in playing How Low Can You Bungalow, a test to see your response to grossly embarrassing personal situations, largely of a lavatorial nature," he said, adding that another game involved avoiding turtle droppings flowing into sewers from various lavatories. "Is that really the stuff of public service broadcasting?" he asked.

Ms Jowell replied, "It is the Government's job to develop a new charter for the BBC. It is then the BBC's job to determine standards of taste, decency and appropriateness."

Today the BBC defended the show, saying it took its public service obligations seriously. It said: "Dick And Dom In Da Bungalow remains one of the most popular shows, which transmits both on the CBBC channel and BBC1.

"The show and presenters won children's Baftas in 2004. It is pure fun and entertainment, aimed at 8 to 12-year-olds, so it is unsurprising that it doesn't appeal to some adults.

"We do take our role as a public service broadcaster very seriously. Any criticisms are always looked into, but have to be addressed in the context of the target audience for the show and its remit to entertain young children."

The show features another game in which the hosts and parents of viewers situate themselves in a quiet public place, such as a museum or restaurant, and take turns to shout "bogeys" at ever-increasing volumes. The game continues until one of them is either laughing too much or too embarrassed to continue.

Presenter Dominic Wood was rapped last year by media watchdog Ofcom for wearing a T-shirt with the slogan "Morning Wood" during the show, which is broadcast on Saturday mornings on BBC1 and on Sundays on the CBBC channel.
