While we await the roll-out of an effective vaccine, other methods of avoiding an over-reliance on lockdowns as a primary policy tool are important, of course, which is why the mass-testing programme being piloted in Liverpool and the example that we had in Slovakia are important. The latest available data shows the weekly rate of COVID in Liverpool is 300 per 100,000 population. The corresponding figures for Merthyr Tydfil, Rhondda Cynon Taf and Blaenau Gwent are all above 400 cases per 100,000 of the population. While bearing in mind the advice of the Scientific Advisory Group for Emergencies that mass testing should complement rather than replace track and trace, is there not a compelling case for the urgent roll-out of a similar mass-testing programme in these areas in Wales? I read today that England is talking about 66 local authorities being part of the next wave of the mass-testing programme. Can you confirm, First Minister, whether the Welsh Government is actively planning a similar programme in these areas in Wales and to do so at scale and at pace?
