The family of missing Madeleine McCann have released the last known photograph of their daughter before her abduction in the Algarve three weeks ago.

The picture shows Madeleine sitting by the swimming pool less than eight hours before she was snatched from her bed.

Taken by Madeleine's mother Kate, aged 38, on her own camera, the picture was taken at 2.29pm on May 3 - Mrs McCann's camera clock is one hour out so the display reads 1.29pm. Less than eight hours later, before 10pm that night, Madeleine disappeared. She had been sleeping in the family's holiday apartment in Praia da Luz, Portugal, when she was abducted.

Mr and Mrs McCann, backed by an army of friends and family, remain convinced that four year old Madeleine is alive and are praying, along with people around the world, for her safe return.
