Explanation:

• At the commencement of the first session of Parliament, whether after the general election to the Lok Sabha, or every year, the President addresses both Houses of Parliament assembled together and informs Parliament of the causes of its summons [Art. 87(1)].
• Each House has to make provision by its rules of procedure for allotment of time for discussing the matters referred to in the Presidential address [Art. 87(2)]. In this discussion, members may raise any question of general policy, public administration and political situation. This discussion provides an opportunity for a general discussion of national affairs.
• The great merit of the debate on the Address from the point of view of the private members is that the field of argument is virtually unlimited, and one can talk about anything under the sun and yet be in order.
• According to the rules of the two Houses, the debate on the President's speech is held in the House on a motion of thanks to the President for his speech.
• Amendments can be moved to this motion. The motion of thanks is regarded as a motion of confidence in the Government. If the motion is defeated, or amended, in spite of the Government's opposition, it may be regarded as a vote of no-confidence in the Council of Ministers resulting in its resignation. 
• The constitutional provision requiring the President's address at the first session of Parliament is mandatory and Parliament cannot be said to have met, and it cannot transact any business, until this preliminary formality has been gone through. The President’s speech essentially highlights the government’s policy priorities and plans for the upcoming year. The address provides a broad framework of the government’s agenda and direction.
