Madeleine was on holiday in the Algarve when she disappeared
Police investigating the disappearance of Madeleine McCann are closing the case, Portuguese media have reported.
Her parents Kate and Gerry McCann are both official suspects in the inquiry, along with a third man, Robert Murat.
But two newspapers claim the police have said they plan to close the case because of a lack of evidence.
Madeleine, of Rothley, Leics, was three when she disappeared in Praia da Luz on 3 May 2007. The family said they were awaiting confirmation of the reports.
The Correio da Manha newspaper said on Tuesday that sources within Portugal's judicial police said they "do not have sufficient evidence to allow formal charges to be brought against the McCanns in the disappearance of their daughter".
The Jornal de Noticias said the police did not have enough evidence to charge either the McCanns or Mr Murat with any wrongdoing.
"The police have not found the guilty," the paper added.
One newspaper said the case had already been closed, while another said the end of the investigation would be announced within the next few days.
McCann family spokesman Clarence Mitchell gives his reaction
The BBC's Alison Roberts, in Portugal, said reports suggested the case had been "archived" or shelved, meaning police would no longer devote resources to investigating it.
She said it could be reopened if new evidence emerged, but officers would not be actively working on it.
The McCanns were declared official suspects - "arguidos" in Portuguese legal jargon - last September.
Their spokesman Clarence Mitchell told the BBC the couple did not know yet whether the reports were correct.
"If they are true, it's to be welcomed that Kate and Gerry are not to face any charges," Mr Mitchell said.
"It's quite right. They are innocent of any involvement in Madeleine's disappearance. They have suffered enough in this process.
"And surely the Portuguese authorities, if this is true, must lift their arguido status as a priority."
Mr Mitchell said the family wanted to know whether police now planned to stop searching for Madeleine.
Surely it's only humane and decent that information that could help find Madeleine comes to the investigators who will keep looking for her
