Competing British police forces 'harmed Madeleine hunt'

Competition between British police forces hindered the investigation into the disappearance of Madeleine McCann and have had a long-term negative effect on the case, according to the author of an unpublished Home Office report.

Its author, Jim Gamble, the former head of the Child Exploitation and Online Protection Centre (Ceop), also told Sky News that so many agencies from the UK got involved with the investigation it damaged relations with Portuguese police.
