Lawsuit could benefit 46 million people even if they have never owned the credit card

Almost every adult in the UK could receive a payout of up to £300 from Mastercard after a court ruling paved the way for a £14bn class action lawsuit.

The legal action taken by former financial ombudsman Walter Merricks claims that 46 million UK consumers paid higher prices in shops over a 16-year period because of allegedly excessive transaction fees charged by Mastercard.
