Lord Frost was Minister for EU relations in Boris Johnson's government in 2021, and before that was the Prime Minister's Chief Negotiator for EU exit and his Europe adviser. He resigned from the government in 2021 in protest against COVID lockdowns and the broader, un-conservative direction of travel. He is now a Conservative Party member of the House of Lords, a writer for the British newspaper The Daily Telegraph, a director of the anti-net zero group Net Zero Watch, and a visiting Fellow at the Danube Institute in Budapest. Before this, he spent most of his career as a professional UK diplomat, with postings in Brussels, New York, Paris, and Nicosia, finishing as British ambassador to Denmark. He was Europe Director at the British Foreign Office and Europe and Trade Director in the Business Department of the UK's Economics Ministry. Between 2013 and 2016 he was CEO of one of the UK’s biggest trade associations, the Scotch Whisky Association.
