From Sky News, hardly 'anti-mccann'

are they ?
But spokesman Clarence Mitchell said evidence from any test would not be admissible in a Portuguese court.
"Kate and Gerry McCann have absolutely nothing to hide," Mr Mitchell said.
"If a request from the Portuguese authorities was made for them to undergo such a lie detector test, they would have no issue with it, provided the test is suitably overseen by an appropriate expert who can ensure the absolutely reliability of the equipment being used."
But he said he understood that such machines were not used in Portuguese criminal cases, nor was the information from them admissible in court.
"Therefore we think it is extremely unlikely that such a request for a test would come through," he added.
The McCanns' declaration that they would be happy to take a lie detector test is just the latest stage of a public fightback to show they had nothing to do with their daughter's disappearance.
The couple, from Rothley, Leicestershire, were declared suspects by detectives after DNA traces were found in a car hired after Madeleine's disappearance.
The couple have returned to Britain after a four-month stay in Portugal and have been told that police do not have enough evidence to justify interviewing them again.
