So according to the Guardian, the government are planning to lockdown students from the 8th-22nd December, with online lectures only.

I've several thoughts:
Some universities finish their terms earlier than the 8th.
What is to stop a mass exodus on the 8th to avoid being locked down?
How can you isolate students who share bathrooms and kitchens? Two weeks wouldn't actually be sufficient. If student A develops symptoms on day 10, the rest of the household would still need to isolate for 14 days from that point.
