KEY POINTS:
Kate and Gerry McCann could be cleared of suspicion over the disappearance of their daughter Madeleine by some nappies, according to The Sun newspaper.
The soiled nappies, worn by the couple's twins Sean and Amelie, were packed into the McCann's Renault hire car when they quickly switched apartments in Portugal.
DNA from the twins and their nappies could have easily been left in the car's boot - and would have been almost identical to missing Madeleine, the newspaper reports.
Up to 30 other people used the hired Scenic before police searched it.
The revelation was made as the couple gave their first interview since returning to Britain, and could seriously effect any case that Portuguese authorities have against the embattled couple.
Other reports indicate that further forensic tests are being undertaken in Britain.
The Sun says the tests are looking for Madeleine's DNA on material gathered from Praia da Luz, including alleged blood samples found in an apartment close to where the couple was staying.
The Forensic Science Service Laboratory in Birmingham is expected to send evidence to Portugal in a matter of days.
A statement released this morning by a Portuguese prosecutor said that the McCanns were not likely to be questioned again as recent interview had failed to make more progress in the case, the LUSA news agency reported.
"New elements of proof - after interrogations on September 7 - have not gathered anything to justify new questioning, so it is not planned," Verao told the agency.
