Diolch, Llywydd. First Minister, in what has been the toughest year in living memory for so many of us, I'm sure we all look forward to a happier new year and, before then, to spending time with friends and family over Christmas. A compassionate but responsible approach to a limited relaxation of restrictions over the holiday period seems sensible. However, it's also crucial that we don't lose the hard-gotten gains of the last few months for the sake of four or five days, and people must, therefore, know that any relaxation also comes with risks, especially in the context of the reversal, potentially, that you were referring to earlier. Can you say what scientific modelling is being used to inform the discussions on a four-nation approach to the Christmas period, and what's your understanding of the likely impact of any easing of restrictions? Given that individual behaviour will be a crucial factor in determining what follows the Christmas break, will the Welsh Government launch a public information campaign, such as the powerful campaigns we see each year on drink-driving over the festive period, encouraging people to follow the guidelines so that we can all enjoy a better 2021?
