A thought:
The UK Gov have declined to have a legally enforceable lock-down.
Call be a curmudgeonly old cynic but we are edging visibly closer to April 6th. Traditionally the Income Tax submission deadline. Proof of history.

With a legally enforceable curfew businesses can claim on their insurance for losses, depending on clauses thereto. Which the insurance companies have recourse on Gov. & a lot of workers' out-of-work benefits are seriously affected.

Curfew too early and people can massage (falsify?() their accounts to favour some advantage.

Now, what is the deadline for company accounts?
