Cabinet Secretary Sir Mark Sedwill has written a letter to Sir Kim Darroch in light of his resignation.
I am deeply sorry to learn of your resignation. Although I understand the reasons for your decision, it is a matter of enormous regret that you were put in this position after a shocking betrayal of trust. I know that public servants in the UK and overseas will continue to be guided by the same values of integrity and impartiality that you have shown in these challenging times.
I thank you, on behalf of the Civil Service and the country, for your outstanding contribution to public life. You have served with distinction in the most senior positions in the Diplomatic and Civil Service - including as the British Ambassador to the United States of America, Prime Ministers’ National Security Adviser and Europe Adviser, and the UK Permanent Representative to the European Union.
You have been an outstanding mentor, colleague and friend. Our country has been stronger for your service. On behalf of the entire public service, I wish you and your family well for the future.
