Here are some facts about the 65-year old:

- He was born in northern England and attended Durham University where he studied zoology.

- He joined the Foreign and Commonwealth Office more than 40 years ago and his career was primarily focused on national security issues and European Union policy.

- Between 2012 and 2015, he was Britain’s National Security Adviser where he dealt with issues such as the rise of Islamic State in Iraq and Syria, Russian aggression in Ukraine, the nuclear threat from Iran and the collapse of government authority in Libya.

- Between 2004 and 2007, he served in Brussels as the British representative to the European Union, representing the government in areas such as the aftermath of the financial crisis and the issues around European integration.

- In 2008, he was made a Knight Commander by the Queen, meaning he could use the title “Sir.”

- In 2015, Darroch moved to Washington as Britain’s ambassador to the United States. In 2016, then President-elect Donald Trump made an unprecedented expression of support for Brexit campaigner Nigel Farage to be made British ambassador to Washington.

The British government dismissed that suggestion saying there was no vacancy.

- In a series of leaked diplomatic cables, Darroch, described Trump as “radiating insecurity” and his administration as diplomatically “clumsy and inept”.

In response, Trump said the United States would no longer deal with Darroch. He later described Darroch as “wacky”, “a very stupid guy” and a “pompous fool”.

Darroch resigned a day later saying the current situation made it impossible for him to carry out his role.
