Gerry and Kate McCann are supporting Missing People's Christmas campaign, which features 12 families who are missing a parent, sibling, son or daughter.
The families involved have had their photos taken by photographer James O Jenkins as part of an exhibition, which will take place in London, titled: Missing People’s Home for Christmas.

The McCanns list of things they miss about Madeleine:
Her sense of humour.
Her imitations of people and characters.
Her voice, her ‘chat’.
That knowing look.
Styling her hair.
Chasing her round the garden.
Sharing her excitement in the run-up to Christmas.
Spoiling her on her birthday.
Shopping with her.
Going to a cafe with her.
Holding her, hugging her, kissing the top of her head.
Lying next to her.
Our complete family of five.
We miss her.
Missing People chief executive Jo Youle said: "For the families of missing people, the thought of Christmas without their loved one is heart-breaking.
"This exhibition will give the public the opportunity to stand with these families missing a loved one, by sharing messages of hope and supporting our annual Home for Christmas Appeal so Missing People can continue to be a lifeline when someone disappears."
The exhibition will open on 14 October and be displayed until 22 November at The Crypt, St-Martin-in-the-Fields, Trafalgar Square.
