LABOUR has demanded to know why the chairman of the Post Office has been sacked although not in charge when hundreds of sub-postmasters and mistresses were unjustly prosecuted during the Horizon computer scandal.

Henry Staunton was appointed Post Office chairman in December 2022, decades after the scandal began, but was sacked on Saturday by Tory Business Secretary Kemi Badenoch.

Labour has questioned the move, saying ministers must explain it.
