British police have returned to Portugal to help interview suspects in the disappearance of Madeleine McCann, according to reports.
Detectives in the Algarve are today expected to begin interviewing a number of key suspects in relation to the three-year-old, who vanished in Praia da Luz in 2007.
It has been suggested that UK officers could sit in on interviews carried out by Portuguese police with up to eight people who will become "arguidos", or people of interest, when they attend a police station voluntarily this week.
All are reportedly Portuguese nationals, although some being questioned are Russian-born, and have been identified by British police as being suspects.
It is thought they include three workers from the Ocean Club in the town of Praia Da Luz, who have been linked to a string of burglaries in the area before Madeleine's disappearance.
