Lindsay Croisdale-Appleby

Lindsay Redvers Mark Seymour Croisdale-Appleby CMG (born 12 May 1973)[1] is a British diplomat and has been nominated in 2021 as the British Head of Mission to the European Union; however, he does not yet technically occupy this position, as he has still not been able to present his letter of credence due to the refusal of the EU to receive his credentials so long as the UK will not grant full ambassadorial status to the EU's representative in the UK.[2] He was Ambassador to Colombia from 2012 to 2015.
