UK Prime Minister Boris Johnson on Thursday appointed Rishi Sunak as his new finance minister to fill the void left by Sajid Javid's sudden resignation. Sunak, 39-year-old Indian-origin, had previously served as the chief secretary to the treasury and is now holds the second most important position in the government as Britain's Chancellor of the Exchequer.

Sunak's appointment was confirmed by the UK Prime Minister in a tweet on Thursday. Sunak's promotion follows a major Cabinet reshuffle - first by Boris after Brexit, which went terribly wrong.  Boris had reportedly demanded Javid fire all of his special advisors, to which the chancellor refused and quit. Sunak worked closely with Javid and was considered his number two.
