I shall happily give the hon. Gentleman that assurance. The continued input of Second Sight is incredibly important, given its familiarity with the case so far and the fact that it enjoys the confidence of many of those involved. It is also important to recognise, however, that to date this system has handled more than 45 billion transactions and that there have been issues with only a tiny, tiny number of them. As the report itself found, the vast majority of sub-postmasters in branches were at least reasonably happy with the Horizon system. I suspect that Members would say that, where IT systems are concerned, “reasonably happy” is probably as good as we are going to get. Generally, it is working well, but we need to ensure that the further work on cases where there are outstanding queries is independent.
Clearly, it has now been ascertained that the Horizon system has problems, even if, as the Minister says, they are not systemic. Does she not feel that that is unacceptable, however, given the delays from Post Office Ltd in working out what went wrong? This matter has meandered on for years, resulting in serious reputational damage risks to sub-postmasters. Will she give us her views on whether that is acceptable?
It is to the Post Office’s credit that it has commissioned this independent review, which has been transparent and accountable, as my right hon. Friend the Member for North East Hampshire (Mr Arbuthnot) also said. It is easy for organisations to say there is not a problem and to try to sweep these things under the carpet, but Post Office Ltd decided to be open about it and to ensure that the report was published. In fact, its newsletter to all branches contained an article encouraging anyone who had difficulties or queries they wanted to raise to ensure they were put into the Second Sight review.
The Post Office has taken significant steps to ensure that there is transparency and accountability and that people’s concerns are taken forward. Clearly, sometimes these issues take time, and of course there are lessons to be learned. Improvements will be made to ensure that when queries are raised, they can be investigated more thoroughly, but again I highlight the context: we are dealing with a system that processes billions of transactions, so it is very complicated and it cannot be expected that nothing will ever go wrong; what is important is how the organisation responds when things do go wrong.
