Cops are supposedly probing a “foreign” man seen in the Algarve around the time of her disappearance in 2007.
Scotland Yard officers have since met with Policia Judiciaria detectives in Porto, Portugal, and are “nearer to knowing what happened to Madeleine”, local media reported last week.
But the missing tot’s parents Kate, 51, and Gerry, also 51, aren’t getting their hopes up.
A family friend told The Sun Online: "They have had their hopes raised then dashed many times in the past so they are not getting buoyed up by any fresh developments. It’s too devastating when nothing comes of it.
