Who tells you that? Of course it does disappear, at least until the next winter. Without lockdown much earlier.

The problem with London are the aristocratic measures of social distancing. The danger of being caughed at at low distance is exponential. The recommendation is 1-2 meter. The UK did 2m, likely because the ones who came with that idea never use public transport, and want to be safe from the plebs. Face masks don't help at all against direct caughing. only against droplets.

2m distancing doesn't work in public places at all. 1 - 1.5m do work, if in the subway, bus, restaurant, pub somehow. I don't know who else did 2m. And the death mortality is directly proportional to the severity of the measures. Maybe not causal, but those are the numbers. 2m don't help at all. When you are being caughed at, it goes far over 5m, even up to 20m. So social distancing in public places does not help much. indirect caughing via droplets is not that dangerous, transmission via surfaces at very low percentages. there's no known case so far. but hard to prove.
