With permission, Madam Deputy Speaker, I would like to update the House on changes to the Post Office Horizon IT inquiry. Over a 20-year period, the Post Office Horizon computerised accounting system recorded shortfalls in cash, which were allegedly caused by sub-postmasters, leading to dismissals, recovery of losses and, in some instances, criminal prosecutions. I know that Members across the House are aware of the terrible impact that this has had on affected postmasters and their families. The life-altering implications of these accounting errors cannot be overstated.
The Post Office Horizon IT inquiry, led by Sir Wyn Williams, was launched in September 2020 as a major step towards righting the wrongs of the past. The inquiry was established on a non-statutory basis to enable the chair to work quickly to establish a clear account of the implementation and failings of the Horizon computer system over its lifetime.
On 27 April, I made an oral statement to the House following the decision by the Court of Appeal on 23 April to quash the convictions of 39 postmasters who had been convicted for Horizon-related shortfalls. As I said then, the Government recognise the gravity of the court’s judgment and the scale of the miscarriage of justice that it makes clear.
Sir Wyn and I are both of the view that the context for the inquiry has changed in the light of the judgment by the Court of Appeal and that now is the right moment to convert the inquiry to a statutory footing. Therefore, I can now inform the House that, with the agreement of the Prime Minister, I will convert the inquiry to a statutory footing on 1 June 2021. I have also agreed that Sir Wyn will now have more time to undertake his work. The inquiry is now expected to report in autumn 2022, rather than summer 2021.
Together, these changes will give Sir Wyn the powers and the time that he needs to conduct an in-depth analysis of the decision-making processes that led to the Horizon scandal. He will be able to compel organisations to provide documents and witnesses to give evidence, under oath if necessary. It is now for Sir Wyn to consider his next steps, and I expect that he will provide more information on his proposed approach soon. In the short term, the inquiry will complete its planned engagements through May, but public hearings that had been expected to take place in June will be delayed.
I have always said that the inquiry should proceed quickly to get the answers that postmasters and their families are seeking. Sir Wyn has gathered a lot of evidence from key parties and engaged with many affected postmasters; I have therefore asked that he provide a progress update to his original timeline of summer 2021, to make public the progress to date and any initial findings. I hope that still more affected postmasters will choose to engage with Sir Wyn as he continues his work on a statutory footing.
The inquiry’s overarching aims—to ensure that the right lessons have been learned and to establish what must change—will remain. However, there will be some changes to the terms of reference in the light of the Court of Appeal judgment. I have today notified the House of the updated terms of reference in a written ministerial statement.
I thank Sir Wyn for his quick progress on the inquiry to date and for taking the time with me in recent weeks to consider the next steps for it. I am pleased to confirm that he has agreed to remain as chair of the inquiry for the next phase.
Finally, I note that converting the inquiry to a statutory footing and proceeding over a longer period will, of course, have cost implications, but I assure colleagues across the House that they are being fully considered with my colleagues in HM Treasury.
The Horizon saga has wrecked lives and livelihoods. We cannot undo the damage that has been done, but we can establish what went wrong at the Post Office and ensure that nothing like it is ever allowed to happen again. The events surrounding the dispute have long been shrouded in darkness, and this Government are determined to bring them into the light. The landmark Court of Appeal judgment changed the context for the inquiry. Following it, the Government did not hesitate to act to give the inquiry more teeth and equip Sir Wyn with more powers. To affected postmasters and their families, my message is that we are listening and we will get to the bottom of this appalling affair. I commend this statement to the House.
