This is just BS, the civil service are still being told to work from home. This is to help out all those office owning, tory voting landlords in London who are concerned about their profits.
The law that requires all people to work from home has gone. Employers can still, of course, require it. The civil service is one such employer.
Of all the corruption scandals recently, this would be the better of them.
Heck in West London the biggest office complex has 20-30% occupancy rates if that. The office at least as recent has been dead.
