Steps to clear the names of hundreds of sub-postmasters convicted in the Post Office Horizon scandal are being considered by the government.
More than 700 people were prosecuted after faulty software made it look like money was missing.
What is the Post Office scandal?
Between 1999 and 2015, the Post Office prosecuted 736 sub-postmasters and sub-postmistresses – an average of one a week – based on information from a computer system called Horizon.
Many maintained their innocence and said they had repeatedly raised issues with Horizon.
But some went to prison for false accounting and theft. Many were financially ruined.
After 20 years, campaigners won a legal battle to have their cases reconsidered.
A public inquiry is ongoing, but many victims are still fighting to have their convictions overturned, or to secure full compensation.
What is the Horizon system?
Horizon was introduced by the Post Office in 1999. The system was developed by the Japanese company Fujitsu, for tasks like accounting and stocktaking.
