In the UK the major parties have a Chief Whip whose role it is keep the party members voting as the leadership want.
The Chief Whip is a political office in some legislatures assigned to an elected member whose task is to administer the whipping system that ensures that members of the party attend and vote as the party leadership desires.
In a democratic system how is this role justified? Common sense suggests MPs be free to vote based on their conscience and based on their constituents' best interests. If there is a role specifically to bully other MPs to vote a particular way, how is that different from more oppressive forms of government?
