Gerry McCann was questioned by police for eight hours
Madeleine McCann's parents plan to stay in Portugal to prove their innocence after being named official suspects in the case, a friend has told the BBC.
Jon Corner said Gerry and Kate McCann, both 39, were determined the search for their daughter would not be "derailed".
The four-year-old disappeared from the McCann holiday apartment in Praia da Luz in's Algarve on 3 May.
Earlier, a family spokesman said police believed Mrs McCann, of Rothley, Leics, had killed Madeleine accidentally.
'Intimidatory' questioning
No bail conditions or charges have been imposed on the couple.
Mr McCann was officially made "arguido" status about 12 hours after his wife. They had been questioned separately for more than 24 hours.
The move allows the authorities to put certain questions to Mr and Mrs McCann, and also gives them the right to remain silent.
Mr Corner said: "I spoke to Gerry in the early hours this morning and he wasn't surprised that he was named as an official suspect.
"The process of questioning I think is designed to be intimidatory, but Gerry is frustrated by the line of questioning and where the inquiry is going.
"But he's also fighting and I think he's determined that the search for Madeleine is not going to be derailed by this."
Is this a ploy by the Portugal Police to close an open case or did they have something to do with it? Would you have left your 3 children aged under 5 alone on holiday? What really is going on do you think?
