Who puts "the government" in place in Great Britain?
God Himself?
George Bush?
Vladimir Putin
Queen Elizabeth?
The Pope?
Little green men in flying saucers from Mars?
The British voters?
The elected representatives of Great Britain, put in power by British voters in free elections, wanted no part of a Republic of Great Britain.
If you do not like that, change the minds of the majority of British voters instead of whining that an institution of Great Britain is "undemocratic" simply because you do not like it but cannot convince the majority of British voters to see things your way.
“The elected representatives of Great Britain, put in power by British voters in free elections, wanted no part of a Republic of Great Britain.”
WRONG
The British government is put in place at the request of the UN-ELECTED monarch. That is how the British system has always worked. The government yes commands a majority of voters in parliament, but if you think that they allow every bill to pass through to a second reading based on actual support for it - you are living in a fantasy world.
Please know the basics of the monarchy and our system before discussing it.
