Detectives investigating the disappearance of Madeleine McCann are expected to begin questioning 11 people today.
British police working on the case are believed to have arrived in the Algarve to take part in interviews alongside Portuguese officers.
They will spend three days working on the case alongside their Portuguese counterparts, according to reports.
ITV News' Rebecca Barry, who is in Praia da Luz, says those set to be questioned "include British and Portuguese men and women, including some former members of staff from the Ocean Club, where the McCanns were staying when Madeleine went missing".
The British police delegation is thought to include DCI Nicola Wall, who has taken over the investigation into Madeleine's disappearance from DCI Andy Redwood, who is retiring.
