Maddie McCann's parents have been left 'angered and upset' after an Australian TV show used old footage of an interviewer asking them: "Did you kill your daughter?"

A friend close to Kate and Gerry McCann has spoken out, saying it is "cruel" and "hideous" to air old clips about them for "shock purposes".

The six-year old footage will be shown on Sunday - just 10 days before the anniversary of Madeleine's death.

A teaser video for Australia's Channel 7's Sunday Night programme also suggests a significant new lead in the case has been unearthed.

 Kate and Gerry's friend said: “It seems cruel for television bosses to be making out Kate and Gerry are on the show and then running old clips of them being asked a hideous question, for shock purposes, about them killing Madeleine.

“This show’s being aired just 10 days before the anniversary and it’s no surprise that Kate and Gerry will be angered and upset.

"They have stated time and again over the years that they had absolutely nothing to do with their daughter’s abduction.

“To be re-running an old interview they did with the network in 2011 as British police finally launched an investigation into Madeleine’s disappearance is quite hideous.”

Brazen documentary-makers are now running a 40-second teaser video using a six-year-old clip with journalist Rahni Sadler posing the "hideous" question.

They are also suggesting in the “landmark television event” they have secured a new interview with Kate and Gerry, which their spokesman Clarence Mitchell said today is “simply not true.”

Mr Mitchell also claimed "there's nothing new" in the programme that he is aware of.

The spokesman was also interviewed for the show five months ago and re-iterated what Maddie’s parents have always insisted.

A source said: “He told them he believes Madeleine could still be alive, that she was stolen and simply could not have wandered out of the apartment herself."

The programme will also feature interviews with forensic scientist Dave Barclay and criminal profiler Pat Brown, who is heard claiming in the promotional video: “They are lying and they are concealing guilt.”

Mr Mitchell is urging film-makers to hand over any new leads to police if they do believe they have any “credible evidence.”

A Scotland Yard spokesperson said today: “We are aware of the TV claims being made and will wait to see what it brings. We cannot talk about ongoing operational matters.”

Three-year-old Maddie vanished from a holiday apartment in Portugal’s Praia da Luz in May 2007 while her parents were dining nearby with friends.

She would now be aged 13, nearly 14.
