Kate and Gerry McCann, the parents of missing Madeleine McCann, returned to Portugal at the weekend to promote the launch of the Portuguese version of Madeleine, the book about the case written by Kate.

In an interview with the Algarve Resident, Kate McCann spoke of how important the release of the book in Portugal is for the case and how she hopes that as many people living in Portugal as possible read the book to help them in their search for their daughter.

Madeleine was released in Portugal today (Monday).

“Someone in Portugal may be holding a key piece of information, knowingly or otherwise,” said Kate McCann.

"Our main goal has always been to find our daughter.".
