Her Majesty’s Government utterly deplore the serious breach of classified information; it is totally unacceptable. As the Prime Minister has already said, we retain full confidence in the British ambassador to Washington, Sir Kim Darroch, for whom we have enormous respect as a distinguished and long-serving diplomat.
The Prime Minister and the British public expect our ambassadors to provide Ministers with an honest and unvarnished assessment of the politics in their country. We pay our ambassadors to be candid, just as the US ambassador here will send back his candid reading of Westminster politics and personalities. But it does not mean that this is the same as what the British Government think. A cross-Government investigation led by the Cabinet Office has been launched, which I can reassure the whole House will be thorough and wide-ranging.
