PRAIA DA LUZ, Portugal (Reuters) - The parents of four-year-old Madeleine McCann, who vanished more than two weeks ago from a Portuguese resort, remain positive she will be found, the priest who married the couple said on Friday.

"They remain very, very positive and will do all that they can to find Madeleine," Father Seddon told journalists at the Praia da Luz resort where Madeleine was abducted 15 days ago.

He said her father, Gerry, had told him he could see light at the end of the tunnel and that everything was still possible.

"Gerry spoke of a tidal wave of destruction that Madeleine's disappearance had caused him but then he said he was met by a tidal wave of empathy and love which has been turned into action and hope," he said.

Chief inspector Olegario Sousa said late on Thursday police continued to follow their strongest lead in the investigation, which has centred on foreigners in the small resort.

So far one suspect has been identified by police -- a 33-year-old who lives in the area -- but his name has not been made public.

The search for Madeleine has received widespread media attention all over the world.

Soccer stars including David Beckham and Portugal's Cristiano Ronaldo have made appeals for Madeleine while wealthy individuals, including author JK Rowling, have offered large rewards for information leading to her return.
