when does the new 20 pound note come into circulation
Bank of England £20 note The current £20 note was introduced in 2007. It features a portrait of Scottish economist Adam Smith on the back as well as an illustration of workers in a pin factory.[3] The note features a number of security features in addition to the metallic thread: these include raised print, a watermark, microlettering, a holographic strip, a see-through register, and a colourful pattern which only appears under ultraviolet light.[4] In September 2015 the Bank of England announced that the next £20 note will be printed on polymer, rather than cotton paper.[5] This was followed by an announcement in April 2016 that Adam Smith will be replaced by artist J. M. W. Turner on the next £20 note, which will enter circulation by 2020.[6] Images on the reverse of the Turner note will include a 1799 self-portrait of Turner, a version of Turner's The Fighting Temeraire, the quote "Light is therefore colour" from an 1818 lecture by Turner, and a copy of Turner's signature as made on his will.[7]
