Attention is once again focused on the Portuguese resort of Praia da Luz where British toddler Madeleine McCann disappeared just over seven years ago.
Reports in the UK have said that police have been given permission to start digging at several sites near where she vanished.
Madeleine McCann went missing from her room in the Algarve resort in May 2007 while her parents were dining with friends at a nearby restaurant.
Police in England launched a review of the case in 2011 and since then have made at least 16 trips to Portugal as part of their investigation into the case.
