My Lords, like a number of noble Lords, I have walked on both sides of the street as a Minister and as a member of the Diplomatic Service. I can testify to the significance to both sides of having frank and unblemished advice from our ambassadors. However, when I became a member of the Diplomatic Service, I was subjected to detailed, developed vetting, to the extent that a bank account my mother had opened when I was eight was uncovered. I am not aware of any equivalent vetting when I became a Minister. Will the Minister give the House a guarantee that, should it transpire that a politician was responsible for these leaks, action will be taken against that politician with the full force of the law in such a way as to ensure that we are not bandying around terms such as “honourable” and “right honourable” without any honour being present?
