It's been years since the extent of the Post Office Horizon scandal became clear - but hundreds of sub-postmasters, who were falsely convicted of fraud or financially crippled in the process, are still waiting for financial redress.Today, key players in the scandal - including former sub-postmaster Alan Bates and recently ousted chairman Henry Staunton - gave evidence to MPs about the government's compensation scheme - and why it's taken so long to pay it.But proceedings were somewhat overshadowed by an unexpected revelation by Mr Staunton. When asked about the investigation into his behaviour while at the Post Office, he claimed the main investigation was actually into current CEO Nick Read.On the Sky News Daily, Sophy Ridge is joined by business correspondent Paul Kelso to discuss the drama unfolding at the Post Office, and Labour MP Ian Lavery who's on the committee looking into the major miscarriage of justice.
