The President, Vice President, Prime Minister (along with other Union Ministers), and Judges of the Supreme Court are required by the Constitution to take oaths or affirmations specific to their respective offices. The Speaker of the Lok Sabha, however, is elected by the House from among its members. They have already taken an oath as a Member of Parliament before being elected as Speaker. There is no separate constitutional requirement for the Speaker to take a fresh oath specifically for the office of Speaker.
