An 'unending nightmare' for Kate and Gerry McCann
July 04 2008 12:54 AM
Kate and Gerry McCann have said they'll take a lie detector test to prove their innocence.
Friends have revealed they want to show they've got nothing to hide over the disappearance of their 4 year old daughter Madeleine.
A friend said: "If they are asked to take a lie detector test by police they would. Kate and Gerry are happy to do anything that will help clear their names."
"They have said all along that they want to co-operate fully with the Portuguese police but, as of today, they have received no such request from the Portuguese authorities."
It comes after prosecutors in Portugal said the pair won't need to return to be re-interviewed, for the time being.
Lie detectors measure physiological responses such as pulse rate, blood pressure levels and skin conductivity when the subject is asked questions. Significant differences in the rates may indicate that the subject is lying.
The McCanns strongly deny any role in the disappearance of Madeleine who vanished from a holiday apartment in the Algarve resort of Praia da Luz on May 3.
The couple, both 39-year-old medical doctors, were with friends at a restaurant just metres away when their daughter disappeared.
Now Kate McCann refuses to take a lie detector test to clear her name

Kate McCann has refused to take a lie detector test about her daughter Madeleine's disappearance, it was revealed yesterday.
She and husband Gerry had offered to undergo a polygraph examination in September, after they were made official suspects in the investigation.
But it has now emerged that they have refused an expert's offer to carry it out, because the results would not be admissible as evidence to a Portuguese court.

Don Cargill, chairman of the British and European Polygraph Association, said the McCanns told him they would only take the test if it was 100 per cent accurate and admissible in a Portuguese court.
He told the Sunday Express: "Kate said she'd take it to prove her innocence but in reality, she wasn't willing.

"I was dumbfounded, to tell the truth.
"I don't think it was the McCanns' fault. I was left with the impression the whole thing was a PR exercise to get sympathy at a time when Kate was under increasing scrutiny."
Lie detectors work by measuring physiological responses such as blood pressure levels, pulse rate, breathing and sweat gland activity in the skin during questioning.
Any significant difference in these rates may indicate the subject is lying.
The process has been criticised but the American Polygraph Association claims the current computerised technology is 98 per cent accurate.
They are not admissible in British or Portuguese courts.
McCann spokesman Clarence Mitchell said: "Of course they are not going to take the test. It's inadmissible in Portugal and there are doubts about the accuracy.
"Gerry and Kate don't need to do one as they are telling the truth."
