Mr Deputy Speaker, we have had three voices of Wales in a row, including yours, Sir. I could not agree more with the hon. Gentleman from Plaid Cymru. The impact of long covid can be very debilitating for many months, and some people who caught covid in the initial peak still suffer from long-covid symptoms. We have instituted more research, and we have started—in England at least—a long covid service in the NHS. Just today, the National Institute for Health and Care Excellence has published an approach to assessing long covid, which I would recommend to the hon. Gentleman. That approach will clearly need continued effort so that we can make sure that people who suffer from long covid get the support they need.
