The Bank of England has presented a new £20 note featuring Adam Smith:
The note features Adam Smith, one of the fathers of modern economics, on the back and incorporates enhanced security features. It is the same size and predominately the same colour as the old-style £20 note that features Sir Edward Elgar on the back.The new-style £20 notes will circulate alongside the old-style Elgar note which will be progressively withdrawn from circulation. The date when its legal tender status ends will then be announced, as is usual practice. As with all Bank of England notes, they can always be exchanged for their face value at the Bank in London.
So the United Kingdom added another reason for not adopting the euro. Brilliant.
