Thank you for your response to Huw Irranca-Davies about the mobile testing centre for Bridgend. I just wanted to ask you, bearing in mind that these regulations are likely to come before us next week and then won't be reviewed for another three weeks from this week, how long do you expect the lockdowns to last? Do you have a time frame in mind, or is it very much predicated on, well, effectively the R number? Thank you.
