Reports that DNA results back up claims that the McCanns were involved in Madeleine's death have been slammed by their spokesman.

Results were reportedly sent to Portuguese police by the Birmingham-based Forensic Science Service which include new evidence of the presence of Madeleine's body in a hire car.

The car had been rented by a number of people, including Kate and Gerry McCann, several weeks after her disappearance from the couple's holiday apartment in Praia da Luz on the Algarve on May 3.

The couple are preparing to mark the six-month anniversary of her disappearance at a special ecumenical church service on Saturday.

Clarence Mitchell said: "This is yet another unsourced, unsubstantiated and possibly inaccurate report and as such we simply won't comment in it.

"However, Kate and Gerry are entirely innocent and therefore are unconcerned about reports in the media because they know the truth."

He added: "They are not responsible in any way, shape or form for their daughter's disappearance.

"Any evidence or material that the police may have that gives them cause for concern, Kate and Gerry can entirely explain with innocent reasons."

Friends of the McCanns have said that any traces of Madeleine's DNA in the car can be explained by the fact that it was used to ferry her clothes and belongings to a new apartment, as well as transferring household waste such as her siblings' used nappies.

The report claims sources have indicated that the volume of material was too great for it to have been transferred from Madeleine's toys or clothing.

Meanwhile, a blonde girl with the same distinctive mark in one eye as missing Madeleine McCann has been sighted in Morocco, Mr Mitchell has said.

According to Spanish private detectives hired by the four-year-old's parents, Gerry and Kate McCann, Naoual Malhi, a Spanish woman of Moroccan origin, saw the child with a woman in the village of Fnidk on August 21.

She asked if she could share their taxi but the woman refused, and Ms Malhi later discovered that the pair had gone to the port of Hoceima.

Mr Mitchell said the woman contacted Spanish police about six days later after seeing media reports suggesting the missing child could be in Morocco.

Sightings of blonde girls resembling Madeleine have been reported across Europe and Morocco but this one is reportedly significant because she apparently had a mark on her iris.

But so far Metodo 3, the Spanish private detective agency hired by the McCanns, has failed to find the girl seen by Ms Malhi.

Mr Mitchell said: "We have looked at this and the police have looked at this, and we still don't have Madeleine back."
