Mubasher: Bank of England (BOE) Governor Mark Carney on Friday said that the UK’s next 50 pound banknote would feature a scientist or mathematician, asking the public to submit nominations over the next six weeks.

The existing 50 pound note features engineer James Watt and his partner Matthew Boulton, who developed and marketed the steam engine in the late 18th century.

Nominations can be made on the BOE’s website until 14 December, while a committee would create a shortlist from the recommendations, and Governor Carney would decide the final figure to appear on the banknote next year.

There are now 330 million 50 pound notes in circulation, with a combined value of GBP 16.5 billion ($21.5 billion).

“I am delighted that the new 50 pound will celebrate the UK’s contribution to science [as] there is a wealth of individuals whose work has shaped how we think about the world,” Carney said at an event at London’s Science Museum.

The UK government said last month that the new 50 pound note would also be made of polymer, which is more durable and harder than paper money.

Under Carney’s leadership, the BOE introduced polymer banknotes, and the first UK polymer note, the five pound note which features World War II Prime Minister Winston Churchill, entered into circulation in September 2016.
