Dame Karen Pierce DCMG has been appointed Her Majesty's Ambassador to the United States of America.
Dame Karen Pierce DCMG, currently Ambassador to the UN in New York and Permanent Representative at the UN Security Council, has been appointed Her Majesty’s Ambassador to the United States of America.
HM The Queen appointed the new Ambassador after the Prime Minister approved the successful candidate on the recommendation of the Foreign Secretary. The request for agrément has now been submitted to the US Government. Karen Pierce is one of the UK’s most experienced senior diplomats and will be the first woman to serve as HM Ambassador to the US.
Foreign Secretary Dominic Raab recently said:
It is a time of huge opportunity for the friendship between the UK and US and I am delighted that Karen Pierce will take forward this exciting new chapter in our relationship. We’re proud to be sending to Washington such an outstanding diplomat, and I warmly congratulate her on her appointment.
Karen Pierce recently said:
I am honoured to have been asked to represent the UK in the US. I think it is the UK’s single most important relationship. There is a deep bond between Britain and the US, built on many pillars.
We have a fantastic cross-Government team across the US and I look forward to working with them to strengthen and even further deepen the special relationship between our two countries and peoples.
Dame Karen will take up her appointment after obtaining the United States’ formal agrément.
Karen Pierce has been the United Kingdom’s Permanent Representative to the United Nations in New York since March 2018. Prior to this role, Karen served as the Director General for Political Affairs and Chief Operating Officer of the Foreign and Commonwealth in London, from 2016.
