The parents of Madeleine McCann have sent a Christmas message to their missing daughter in a new video appeal for information.
Kate and Gerry McCann say their only Christmas wish is to have their daughter back.
Madeleine, four, vanished from the family's holiday apartment in Praia da Luz, Portugal on 3 May.
The couple remain official suspects, but have always denied any involvement in her disappearance.
'Despair and anguish'
The worldwide appeal, recorded at their home in Rothley, Leicestershire, includes previously unseen clips of Madeleine filmed last Christmas.
The McCanns promoted an appeal hotline number
In one she is shown opening a parcel containing a pink suitcase which she took on holiday in May.
The couple believe their daughter is still alive, and have employed private investigators in their search for her.
In the first part of the video the couple talk about the possibility that someone knows what happened to their daughter.
They make a direct appeal to such a person to end their "despair and anguish".
Mr McCann says: "This special time of year is all about families coming together with love and peace.
"Clearly for us and the rest of our family it's going to be the hardest Christmas imaginable without Madeleine here."
Appealing for information, Kate McCann says: "You must understand that you hold the key to ending all this despair and anguish, for both us and Madeleine.
"At this time of year, when so many families are coming together we beg you to help us be reunited with Madeleine.
"Please do the right thing and come forward."
Speaking directly to Madeleine, Kate McCann said it "seems unlikely that you'll hear this but, just in case, it's Mummy and Daddy here...
"Just know how much we love you, Madeleine. We all miss you so much."
She said Madeleine's brother and sister, two-year-old twins Sean and Amelie, "talk about you all the time every day".
Mrs McCann added: "We're doing everything we can, Madeleine, to find you and there are so many good and very kind people helping us.
"Our only Christmas wish is for you to be back with us again and we're hoping and praying that that will happen."
The couple appeal for anyone with information to call a confidential hotline run by a Spain-based private detective agency.
