My hon. Friend is exactly right—we are going as fast as we can. I recognise the importance of this. There was spare capacity earlier in the summer. We have maintained the turnaround times—they are very rapid—but there have been challenges in the last couple of weeks because of that increase in demand and some of the operational issues that we have discussed. He is right to raise this, and he has raised it with me privately before. There is no one more assiduous in putting forward the needs of their constituents than my hon. Friend, and I will keep him posted on how much we can expand testing in Buckinghamshire.
