Horizon was the faulty computer system which led to hundreds of Post Office staff being wrongly convicted of theft and false accounting - some went to prison.

The system was incorrectly showing shortfalls of money.

It has been described as one of the biggest miscarriages of justice in recent history. Prime Minister Boris Johnson promised an independent inquiry into the Horizon scandal.

Seema Misra and Tracy Felstead were two of those who went to prison. They speak to the Sky News Daily before giving their evidence to the inquiry.
