This means that all Cabinet members are held accountable for the actions and policies of the government, regardless of whether or not they personally agree with them. Collective responsibility ensures that the government functions as a cohesive unit, with all members working towards the same goals and objectives. It also promotes unity and stability within the government, as it discourages public disagreements or dissent among Cabinet members.
