London will likely be shutdown and in chaos within a month.

I have some inside intel on this. Can't give too many details but I have a friend of many decades who works for a UK ministry.

He called me a few days ago out of the blue and we discussed contingency plans in detail. He has a young child and is planning to leave the city or at least get his wife and kid out.

I am in another European country and we are cancelling a trip to the UK scheduled for a large group in April. We are taking a substantial financial hit on the cancellation.
