The whip system, also known as party discipline, is a fundamental feature of many political systems around the world. It refers to a method used by political parties to ensure their members' adherence to the party's stance on a particular issue or policy. In simple terms, the whip system is a mechanism to maintain party unity and loyalty.

The whip system functions through the appointment of party "whips" who are responsible for enforcing party discipline and ensuring members vote in line with the party's official position. These whips have the authority to persuade, cajole, or even pressure party members to vote in the desired manner. They also keep a close eye on attendance during important votes and regularly communicate with party members to gauge their views on upcoming legislation.

While the whip system has its critics who argue that it stifles individual conscience and independent thinking, proponents argue that it ensures the smooth functioning of political parties and allows them to effectively pursue their policy agenda. Ultimately, the whip system is a tool used by political parties to maintain cohesion and unity among their members, balancing party loyalty with individual member representation.
