Kate and Gerry McCann have said this Christmas - their 10th without their missing daughter Madeleine - will be "inevitably tinged with pain and longing".
They hope support from others would "keep us strong and afloat during the difficult months to come".
Madelaine was three-years-old when she disappeared from the family's holiday apartment in Praia da Luz, Portugal, in 2007.
On May 3, it will be 10 years since her disappearance.
The couple added: "There are no words really. Suffice to say, we will try and make [this Christmas] as happy a family occasion as possible."
The Metropolitan Police have been assisting the family with the search for clues and visited the holiday resort in 2014.
