Two people are being re-interviewed by Portuguese police in connection with the disappearance of Madeleine McCann.
The investigation is continuing into the abduction of the four-year-old in the Algarve 20 days ago.
It is believed the pair are the German girlfriend of the sole official suspect, Briton Robert Murat, and her estranged husband, a Portuguese national.
Meanwhile, Madeleine's parents Gerry and Kate McCann have visited Fatima, Portugal's holiest site, to pray for their daughter's return.
