Kate and Gerry McCann vow to do 'whatever it takes' to find Madeleine

The parents of Madeleine McCann have vowed to do "whatever it takes for as long as it takes" to find her as they prepare to mark the tenth anniversary of her disappearance.

In a wide-ranging interview ahead of next week's anniversary, Kate and Gerry McCann also said they intended to challenge a court ruling clearing a Portuguese former police officer of breaching libel laws.
