Mark Carney was the first non-British person to become governor of the Bank of England in its more than 300-year history when he took the job in 2013.
He had previously worked at the investment bank Goldman Sachs, and served as the governor of the Bank of Canada, the country's central bank.
He took over there in 2008, a few months before the peak of the Great Financial Crisis - and his success in that role paved the way for a move to London.
He had long-standing connections with the UK, having studied for two degrees at Oxford University and married an English woman.
In his time at the Bank's Threadneedle Street headquarters, he oversaw considerable changes in how the Bank worked. At the start of his tenure, the Bank assumed responsibility for financial regulation after the abolition of the Financial Services Authority.
He is credited with modernising the Bank, appearing much more frequently in the media than his predecessor.
