Use of court expert witnesses needs 're-think'

There have been calls for a re-think on the use of expert witnesses in the family court system.

The head of Children's Services at three central London local authorities has warned that a lack of regulation is causing unnecessary delays, wasting money and could lead to wrong decisions being made by judges.

BBC London's Kurt Barling talks to Andrew Christie, director of Children's Services, and Dr Judith Freeman, of the Consortium of Expert Witnesses.
