'It captures so much of Turing's work': Bank of England unveils new £50 note – video

A new 50 note featuring Alan Turing, the scientist best known for his codebreaking work during the second world war, has been unveiled by the Bank of England and will go into circulation on 23 June, the date of his birth.

Turing was prosecuted for homosexual acts in 1952, and an inquest concluded that his death from cyanide poisoning two years later was suicide.

The Bank of England governor, Andrew Bailey, said: I'm delighted that our new 50 features one of Britain's most important scientists ... He was also gay and was treated appallingly as a result. By placing him on our new polymer 50 banknote, we are celebrating his achievements and the values he symbolises."
