The westminster has only 8 questions but they seem to cover different topics.
Few are about the Westminster system of government:
Some are about the UK specifically:
One is mostly about a different topic (historic English influence on Scottish politics):
The tag excerpt isn't very descriptive either, it mostly introduces it as a synonym to united-kingdom (some tagret on whoever wrote that no doubt):
Westminster is an area in Central London that's often used synonymously with the UK Government. Consider using with the following tags: [united-kingdom], [house-of-commons] or [house-of-lords].
My suggestion is as follows:
Remove the tag from questions not about the Westminster system
Rename the tag to westminster-system
Add an excerpt that emphasizes the tag should be used when the question is about the Westminster system in general or comparing multiple implementations rather than one country's implementation (in which case the country tag suffices).
Add the tag to other questions that fit this description. For example,
- In a Westminster system, why would the PM voluntarily dissolve a majority government?
- Has there ever been a situation in a modern Westminster parliament where there have been more independents than members of the second largest party?
- Opposition members in cabinet
- Has a party that won an election ever lost its leader in the process?
