The Bletchley Park codebreaker Alan Turing is to be the new face of the Bank of England’s £50 note.

Turing will replace James Watt and business partner Matthew Boulton. The bank used a humorous animation – featuring Watt and Boulton – to reveal the news.

The Bank said the new Turing note is expected to enter circulation by the end of 2021.

Mark Carney, Governor of the Bank of England, said: “Alan Turing was an outstanding mathematician whose work has had an enormous impact on how we live today. As the father of computer science and artificial intelligence, as well as war hero, Alan Turing’s contributions were far-ranging and path-breaking. Turing is a giant on whose shoulders so many now stand.”
