Michael Portillo has said Wikileaks has given clear evidence of crimes being comitted "on an industrial scale" in Iraq by the US.
He was debating Max Mosley's film on secrets and privacy with Kate Hoey, Mr Mosley and Andrew Neil.
Portillo said the internet kept people more honest, but authorities could be working harder to stop future leaks.
Mr Mosley said authorities should publish everything they could without jeopardising an operation.
