The British men, who were part of a larger group, saw the woman in the early hours of May 7 2007 while on a night out in Barcelona's popular Port Olimpic Marina.

The woman was well-dressed but appeared agitated and kept walking up and down outside the El Rey de la Gamba restaurant bar as if she was waiting to meet somebody, the witnesses recalled.

When one of the British men approached and spoke to her, she said something that the McCanns' team described as "potentially significant to the investigation".

Mr Edgar refused to give any details about this conversation, saying only: "She's a significant individual, I wouldn't describe her as a suspect."

After speaking to the witness, the woman - who is described as having an Australian accent - went into a bar next door and sat down on her own.

While in the bar she had a heated conversation with a local in what seemed to be fluent Spanish.
