A previously unpublished report into the disappearance of Madeleine McCann says the investigation was hampered because different police forces were competing against one another.
The report from Jim Gamble, the former head of the Child Exploitation and Online Protection Centre, also attacked the decision to put Leicestershire constabulary in charge of the probe.
Mr Gamble said the force was not properly equipped to deal with such a wide-ranging investigation.
According to Sky News the report, originally commissioned in 2009 by then Home Secretary Alan Johnson, led the Metropolitan Police to re-open the investigation in 2011.
