Kerry wants Interpol to review case of missing Ben

Greek police have already questioned the woman about her movements when the 21-month-old toddler disappeared from outside a farmhouse his grandparents were renovating in 1991.

But Kerry claims they bungled the inquiry and she won’t rest until Interpol step in and review reported sightings of the woman’s car at the remote farmhouse where Ben was last seen alive.

A witness alleges he saw three people parked in a vehicle next to the farmhouse shortly before Ben disappeared.

The middle-aged woman who owns the car has fuelled Kerry’s suspicions by offering conflicting explanations about the whereabouts of her car on that afternoon.

Kerry travelled to the island just weeks ago to try and investigate the matter herself - and claims relatives of the woman hurled abuse at her when she tried to question them.

She also claims island police gave her the brush off when she turned up uninvited at the local headquarters and tried to raise the issue.

She says senior officers wouldn’t let her inside the building and only spoke to her “very briefly and reluctantly” in the courtyard outside the police station.

Kerry says the disappearance of four year old Madeline McCann had inspired her to contact Interpol about the woman’s involvement in the case.

She has also written to Gordon Brown and the Greek Prime Minister urging them to review the case.

Kerry, aged 35, says she understands what Madeline’s parents are going through better than anyone.

“Madeline’s family have been given every bit of support since she vanished, and I don’t begrudge them any of the help they’ve got – but it’s time that we got the same kind of backing too. I think that Ben is still out there somewhere.”
