Question

All the members of
parliament are not a
part of the ruling
government. Why?​

Answer 1

Explanation:

A member of parliament (MP) is the representative of the people who live in his/her constituency. In many countries with bicameral parliaments, this category includes specifically members of the lower house, as upper houses often have a different title. Member of Congress is an equivalent term in other jurisdictions.

Members of parliament seem to tend to form parliamentary groups (also called parliamentary parties) with members of the same political party
