Gerry McCann says he is "encouraged" by new evidence relating to the disappearance of his daughter Madeleine.
"As parents, we won't accept Madeleine is dead until we see clear evidence that that is the case," he told ITV News.
"Clearly we're encouraged. There is new evidence, and the appeals will hopefully lead to further new evidence."
He said he and his wife were "optimistic that new pieces will be uncovered that will fill in parts of the jigsaw."
