The Bank of England has a set of criteria for choosing characters for banknotes – initially, it looks at who has previously featured, to allow for a reflection of the diversity of society. It does not accept fictional characters, or anyone still living (with the exception of the reigning monarch), but instead aims for individuals that are both widely admired, and are considered to have made an important contribution to UK society and culture. The final criterion is that the individual has an easily recognisable portrait available for use. This does not need to be a painting, as, up to , there have been two sculptures and a photograph used.
