THE father of missing Madeleine McCann says he is "100% confident" his wife had nothing to do with her disappearance.

Gerry McCann used his blog on the official Find Madeleine website to speak of the "unending nightmare" of the past week.

He and his wife Kate were declared official suspects by detectives in the case before making the agonising journey back to Britain with their two-year-old twins - but without Madeleine.

Meanwhile, police in Portugal are this morning playing down reports that DNA found in the family's hire car was a 100 per cent match for the missing girl.
