Postmasters call for retrial of convicted murderer

Postmasters support retrial plea for convicted murderer amidst calls for re-examination in light of the Post Office Horizon IT scandal. Robin Garbutt was convicted in 2011 for his wife's murder, with faulty Horizon software playing a key role in the trial. Former sub-postmasters, including those wrongly accused due to the IT system, back Garbutt's appeal for a new trial, raising questions about the reliability of evidence against him.
