Kate and Gerry McCann said today they still believe their missing daughter Madeleine is alive and it will only take one piece of information to find her.
The couple appeared on GMTV in a live TV interview as they began a new media campaign in their search for the little girl, who vanished nearly a year ago.
Mr McCann said their ordeal has been “almost unbearable”, but they have been pulled through by their young twins Sean and Amelie.
He said: “Any parent will understand we will do anything to get that child back. We will go to the ends of the earth.”
Wife Kate added: “We’re Madeleine’s parents; if we’re not there for her, who is?”
They have not yet decided what to do to mark the first anniversary of the four-year-old’s disappearance from Praia da Luz, Portugal, on Saturday.
Mr McCann said there are nights when he thinks “I don’t want to wake up tomorrow”, but that they believe a lot can still be done.
He added: “That person’s still out there and will probably do this again.”
Speaking of the hate mail the couple have received he said: “The negatives do drag you down a bit, you try to develop a thick skin and put them aside. The problem with the recurring criticism that we went to dinner 50 yards away is that we can’t change that.”
Mrs McCann said: “Everybody parents in a different way. I couldn’t love Madeleine more than I do and there’s no way we would ever take the risk. There’s probably some things that other people do that we wouldn’t do. There’s no right or wrong, it’s just different.”
The couple gave the number of a dedicated phone line for information about Madeleine’s whereabouts, 0845 838 4699.
GP Kate added: “There’s been an evil crime committed here, a hideous crime ... It’s just so important to concentrate on that. ”We’ve got to live with ourselves for that misjudgement but really the focus should be on that person who’s out there.“
She said they will never stop looking for their daughter.
