The parents of missing Madeleine McCann have given their first TV interview since being named as official suspects in their daughter's disappearance. Kate and Gerry McCann appeared on a Spanish station to announce the launch of a phone line for anyone with information about the four-year-old. Mrs McCann broken down in tears towards the end of the interview as she talked personally about Madeleine. "I feel sad and I feel lonely and our life is not as happy without Madeleine," she said. "I feel anxious she is not with us." Asked about the last time she saw Madeleine, she said: "She was very happy and very loving and I know Madeleine was very happy with her life. She is special." Mrs McCann was also asked if she was as confident now of finding Madeleine alive as she was on the day she vanished from her family's holiday apartment in Praia da Luz, Portugal. She replied: "Maybe even more so. I think she is possibly being held by someone in their house but I don't know. "As Madeleine's mummy I feel in my heart that she is there. I don't know how anyone could harm anyone as beautiful as Madeleine. I don't mean her appearance. I mean as a beautiful person." Asked how their other two children, two-year-old twins Sean and Amelie, were coping, she said: "They do ask about Madeleine. Madeleine was very much a big part of their life. They are not upset and they are not distressed but they are very much aware she is not there." Mr McCann said: "The hardest thing for me is when they [the twins] say, 'When is Madeleine coming back home?' and we have to say, 'We don't know but everyone is looking for her'." The McCanns reportedly chose Antena 3 ahead of more well known broadcasters such as Oprah Winfrey and Barbara Walters for the interview because they believe their daughter is most likely to be in Spain, Portugal or north Africa. They urged people from that region to dial 00 34 902 300213 on a confidential, 24-hour phone line manned by private investigators if they have any information about Madeleine. The couple have received the backing of the Portuguese police in launching the initiative. The McCanns' spokesman Clarence Mitchell has announced the phone line has already drawn a good response. He said: "I can confirm we have already had a very good response to our confidential, anonymous phone line in Spain. "However, we will not be commenting on the volume of calls being received or whether any fresh lines are being pursued. "As this is a private investigation it will remain exactly that - private."
