Do £50 notes pass the market trader test?

The Bank of England has released a new £50 note featuring entrepreneur Matthew Boulton and engineer James Watt.

The Bank says the note will have a range of enhanced security features.

But market traders told the BBC's Simon Gompertz that they would prefer it if people did not pay with £50 notes as they could be counterfeit.
