Its security features make it 'very difficult to counterfeit'
Britain's "most secure" banknote will be in our hands in February.
The Bank of England unveiled the new £20 that will be "very difficult to counterfeit" due to it incorporating advanced security features.
The polymer note, featuring artist JMW Turner, two windows and a two-colour counterfoil, was announced by Governor Mark Carney.
It will join the Churchill £5 and the Austen £10 already in circulation, and will be followed by a new £50 note featuring Alan Turing in 2021.
The current paper £20 notes were at the centre of a spike in scams on Teesside in April.
Forgers targeted a takeaway, supermarket and an elderly man with counterfeit notes.
The public will begin to see the new £20 from February 20 next year as the notes leave cash centres around the country and enter general circulation.
Paper £20 notes can be spent as usual as they are gradually withdrawn as legal tender.
Governor Carney said: “Our banknotes celebrate the UK’s heritage, salute its culture, and testify to the achievements of its most notable individuals.
"And so it is with the new £20 banknote, featuring JMW Turner, launched today at Turner Contemporary in Margate.
"Turner’s contribution to art extends well beyond his favourite stretch of shoreline. Turner’s painting was transformative, his influence spanned lifetimes, and his legacy endures today.
"The new £20 note celebrates Turner, his art and his legacy in all their radiant, colourful, evocative glory.”
