Madeleine's parents still hopeful

The parents of missing Madeleine McCann say they still believe they'll find their daughter.

In their first TV interview since she went missing three weeks ago, Gerry and Kate McCann said they needed to believe Madeleine would come back to them.

Madeleine disappeared from her family's holiday apartment in Praia de Luz on 3 May, while her parents were out nearby.

Police said they were now looking for a man in his 30s, who was seen in the area on the night Madeleine vanished.

Madeleine's parents described her as a very funny, lively and sociable little girl and said discovering that she was missing had been a "nightmare".

They said her younger brother and sister were coping well with the situation but they wanted their older sister back.

Strong belief

Mr McCann said: "We need to bring Madeleine back as much for them, as for Madeleine, as for us.

"If anything bad had happened we would have found her by now so I think, and I believe this strongly, that we will find her.

"She's our daughter, we love her more than anyone can imagine and the alternative would be giving up and we will not give up our search."
