There appears to be increasing tension between the German, Portuguese and British police about who knew what and when about the new prime suspect in the Madeleine McCann case, Christian B, who is being held in a prison near Hamburg.

The Portuguese police say his name was on a list of hundreds of potential suspects handed to the Metropolitan Police in 2012 when the force was preparing its own investigation, but Scotland Yard didn't act on the information.

A German prosecutor insists he has evidence Madeleine is dead and has launched a murder investigation, while Scotland Yard says it still considers Madeleine a missing person.
