It's May and her 10th birthday. Space will have been reserved in press calendars, particularly in the tabloids. They've got to fill it up with something.
Some of these leads haven't been followed through to elimination. Even your average hack can work that out.
Yes, I understand that there are times when we can expect more than usual press coverage ( Madeleine's birthday for instance )
The point I am making, though, is that the old stories being rehashed at the moment have a common theme ... they are being 'spun' to suggest Scotland Yard have uncovered new leads that where previously unknown
This particular story ( quoted in the OP ) has been confirmed by a source 'close to the McCanns' as being 'new' information that they considered a 'development'
The reader is left with the impression that Scotland Yard have uncovered evidence that the McCanns were previously unaware of ... when, in reality, they ( and we ) have been aware of this information for years
