Members of the so-called Tapas Nine who dined together on the night Madeleine vanished could also be asked to return to Portugal for meetings and to aid "identification", sources close to the investigation said. The move by police is the clearest indication yet that they still consider there are serious allegations for the couple to answer.
Police sources said that three Policia Judiciaria investigators are poised to fly to Britain next week to question the couple and their holiday friends again about missing Madeleine.
A decision will then be taken on whether to recall the McCanns to the Algarve after they are re-interviewed in Britain, the Portuguese newspaper Correio da Manha reported.Portuguese police have already prepared requests to re-interview the parents and their friends in Britain and a source close to the case told the newspaper: "In the letters which are practically ready and should follow on this week, there may be more things asked other than the questions that will be done there."
The police source added: "When the operations begin on British soil we will determine if it is necessary to bring someone to Portugal. It may be necessary to do some identification or confronting of witnesses because it is not certain that all will be interrogated there. The decision will be made depending on how the operations go. It is confirmed that the letters will still proceed this week." (Daily Mail)
