You've just confirmed that you have commissioned some new scientific work on the transmission of the new variant of the virus among children. Before receiving the result of that work, how can you be confident that the education Minister's plans to get everyone back to school by 18 January is wise and sustainable in terms of preventing the spread of this new variant? Aren't the signals currently suggesting that we should reconsider that policy and maintain on-site learning for smaller groups only beyond 18 January? If it's inevitable that schools will have to be closed for the majority of pupils, then, please, inform schools in good time. If closure is inevitable in order to prevent transmission, then we need to provide adequate warning so that teachers can prepare to teach as best as they can and for families to make their own arrangements too.
