A public inquiry opened formally on Monday into the faulty IT system at the Post Office which led to the most widespread miscarriage of justice in British legal history. More than seven hundred Post Office managers were wrongly convicted and thousands of others lost their businesses when the accounting software, Horizon, wrongly showed that money was missing from branch tills. The wrongful convictions of hundreds of sub-postmasters and mistresses will be examined by the inquiry.

Today's Mishal Husain spoke to BBC correspondent Colletta Smith, as well as Myra Philp, whose mother who ran the post office in Auchtermuchty in Fife and died in 2018 before the first case won by postmasters. Mishal also spoke to Nick Wallis, who started looking into the postmasters stories 12 years ago and presented the Radio 4 series 'The Great Post Office Trial'.
