This so-called 'pinging' is causing chaos in every walk of life. Supermarkets warned the rising number of retail workers being forced to self-isolate was beginning to affect the availability of some products. The Co-op said it was "running low on some products", while Iceland said shops might have to be shut. Sainsbury's said it "might not always" have the exact products people wanted, but downplayed fears of shortages, saying the problem was not widespread. Iceland also urged shoppers not to panic buy, saying it was not necessary. Business Secretary Kwasi Kwarteng said the government was "concerned about instances of shortages". "I don't want people to get the impression that every shelf in every supermarket is bare - that is not the case but we are certainly concerned about instances of shortages, we are looking at the supply chains of critical industries and we are reviewing that situation," he added. The Government is looking at extending the list of those who do not have to isolate for 10 days if pinged, and not before time. This whole thing is ridiculous. Regrettably, a body representing police officers reacted angrily to the news that those earning over £24,000 would not get a pay rise due to financial pressures caused by the pandemic. The Home Secretary gave a robust defence via the Home Office, which said she had demonstrated her commitment to police "time and time again". A spokesperson added that Ms Patel had given them "the resources and powers they need to fight crime and protect the public". I empathize with the police who have had a rough ride in recent months, but the fact is the country is deeply in debt, with the risk of inflation and rising interest rates threatening. Among other things today, I had a most interesting virtual meeting with Eric Briar, the MD of Manor Renewable, based in Portland Port. He and a colleague updated me on how the company was progressing, which was all very promising, and briefed me on two potential offshore wind farms, one off Portland, the other off Lyme Bay, both a long way out and out of sight, thankfully. They are also looking for potential solar farm sites. The former would be good for Portland Port, jobs, etc, and being so far out I was far less worried on the impact on our Jurassic Coast, which the Navitus Bay project would have blighted. I then attended a virtual surgery. I was delighted to hear that sub-postmasters wrongly convicted of offences in a Post Office IT scandal would get interim compensation of up to £100,000. As of this week, a total of 59 former sub-postmasters have had their convictions quashed - with more due in court over the coming months. More people have been affected by the scandal than in any other miscarriage of justice in the UK. The government has agreed to fund the initial payments. This was an outrage and I have the deepest sympathy for all those affected.
