A petition backed by tens of thousands is demanding the parents of Madeleine McCann undergo a lie detector test.

Madeleine disappeared almost a decade ago while on holiday with her parents Kate and Jerry in Portugal.

More than 27,000 people have signed a petition calling for the test so far, and the petition's organisers want 100,000 signatures so they can take it to Parliament, The Sun reports.

Madeleine would now be aged 13, if she is still alive, and would turn 14 on May 12.

She vanished from the family's holiday apartment while her parents were having dinner in a nearby restaurant.

In October 2015, the case investigating her disappearance was scaled down from 29 to four detectives.

The hunt to track her down has cost almost £12 million ($21 million) to date, and her parents say they will never give up hope of finding her.

They have consistently fought back against media reports and suggestions that they had a role to play in her disappearance.

In February the Portuguese Supreme Court ruled they had not proved they were innocent, and the McCanns fought back calling the ruling "nonsensical".
