What characteristics does Great Britain have that makes it a democracy?
None whatsoever. The United Kingdom (there is no such country as “Great Britain”) is primarily a *republic*, which is very different from a democracy. A republic is a system where the country is primarily governed by elected representatives. The UK has a group of representatives called ‘Parliament’. A democracy is a system where the citizens make all decisions by ballot. The UK does not make decisions in that manner.
It’s not a democracy. It’s a democratic monarchy. England has a Queen. All Britons are here subjects. They are not citizens. The monarch ceded much power when the Magna Carta was signed, so England now has a parliament, made up of the House of Lords and the House of Commons. MPs are elected. The head of government is the Prime Minister, who is usually the head of the majority party in Parliament. The Parliament makes the laws much as the Congress does in the U.S. The Prime Minister is similar to the U.S. President. The big difference is that the monarch (the Queen) has the power to dissolve Parliament. Ther is no U.S. correlation to that.
