A minister controls public corporations by

A minister controls public corporations by giving general policy directives. As a political head of a ministry, a minister is responsible for setting the overall policy direction for the public corporations that fall under his or her jurisdiction. The minister would work closely with the management of the public corporations to ensure that their operations are aligned with the policy objectives of the government. The minister may also oversee the appointment of the board of directors and top management of the public corporations, and would have the power to make changes if necessary. However, the minister is not expected to undertake day-to-day administration of the corporations or audit their accounts personally. Rather, those tasks are typically delegated to the management and board of directors of the public corporations.
