My friend, Justin Madders, says from a sedentary position that that was his idea, but success has many fathers and I can tell my hon. Friend Dr Evans that such a postcode checker was launched this morning. I will send him the link. It is still in beta, so it will be constantly improved, not least to ensure that, if a postcode covers an area that is in two different levels, that is clear. That is being sorted at the moment. A postcode checker is a great idea. It tells you the level of local risk. Furthermore, the NHS covid app, which has now been downloaded by over 17 million people, has a link to the local alert level as well.
To turn back to the measures before us, we will keep the measures under constant review. The overarching regulations sunset after six months, but regulation 8(1) of statutory instrument 1105 makes clear that the allocation of a particular area to local alert level 3 will automatically expire after 28 days. We will work with local areas on the level they need to be at and that work continues at pace. Decisions to move local areas between the levels will be considered by the JBC, working across Government and with local government on the normal weekly cycle. While, of course, there will be times when we need to act quickly to contain the virus, we want to give the House the opportunity to consider the measures on the medium and high local alert levels, and the baseline measures for the very high alert level. I urge the House to support the measures set out today.
