Sir Alan Bates is a former subpostmaster and a leading campaigner for victims of the British Post Office scandal, in which thousands of subpostmasters were accused of dishonesty when faulty Post Office accounting software created shortfalls in their accounts. After the Post Office terminated his contract in 2003 over a false shortfall, he sought out other subpostmasters in the same position and went on to found the Justice For Subpostmasters Alliance in 2009. The group took the Post Office to court and, following two favourable judgments in Bates & Others v Post Office Ltd, accepted a settlement of £57.75 million, which left the 555 claimants with little money after legal fees were paid. Bates has continued to campaign for fair compensation for subpostmasters. He was knighted in June 2024 for his campaigning and the following month received an honorary degree from Bangor University.
Victims of the Post Office Horizon scandal have been urged to take legal action against the government over compensation delays.
