The ridiculous idea of this government to allow the return of Imperial measures, as some sort of reward or benefit of Brexit tells you a lot. If this is the kind of benefit that comes to its mind, it must be pretty desperate. The costs whichever way you measure them are huge and this is just window dressing for Brexit extremists.
It is also a sign that Brexit was and is a policy of the elderly, they voted overwhelmingly for it and they are pretty immune to its consequences. They are not exporters or farmers or young people who want to live and work across a whole continent and now they get nostalgia as well. Already there have been letters in the press calling for the return of pounds, shillings and pence, on the grounds that it is good for mental maths and decimalisation was a cunning EU trick that was forced on an unwilling country (it had nothing to do with the EU.)
This is all part of the same wave that Brexit rode and the clue is in the name.
Imperial measurements, it has the word imperial in it, so it must be good, a sign the UK is once again a world power, a reminder of past glory etc etc.
For the few people old enough to remember the Empire this might be attractive, although I think they are actually more realistic. For the rest of the elderly this is some sort of security blanket, a way to deny the relative decline of the UK in their lifetime. It is all damaging, dangerous and deeply ignorant of the UK’s past.
If you want to know how inglorious the British Empire really was I suggest reading The Anarchy by William Dalrymple, about the East India Company.
A brilliant book on a shameful subject.
Economics, trade and Brexit, not necessarily in that order but the dog always comes first.
Don't tell them it's Roman Imperial.
