A parliamentary secretary is a member of parliament in the Westminster system who assists a more senior minister with their duties. In several countries, the position has been re-designated as assistant minister.
In the parliamentary systems of several Commonwealth countries, such as the United Kingdom, Canada, Australia, India and Singapore, it is customary for the prime minister to appoint parliamentary secretaries from their political party in parliament to assist cabinet ministers with their work. The role of parliamentary secretaries varies under different prime ministers. The post has often served as a training ground for future ministers.
