The UK faces another national lockdown “in short order” unless people abide by new COVID-19 restrictions, a government adviser has told Sky News.

Peter Openshaw, a professor of experimental medicine at Imperial College London said:

“I think everyone is in agreement that we really need to act very quickly now in order to prevent this from growing exponentially and that’s the main point, is that we must act fast because it is so much harder to get this sort of thing under control if you delay even a few days.

“This is potentially going to be quite dangerous now at this particular moment.”

He added: “But if we don’t do this now we are going to be right back in hard lockdown in short order, that’s the only way we have at the moment for controlling this but there are other things on the horizon.

“We need to act quickly. This isn’t a game. We shouldn’t be out trying to¬†party as hard as we can in the run up to Monday’s lockdown.

“We should all be thinking about what we can do to slow down the spread.”
