In numbers: 20 Oppn parties take on Modi govt but how do they stack up against BJP in Parliament?

Apart from these 19 parties, the All India Majlis-e-Ittehadul Muslimeen (AIMIM) has said it will not attend the event. The Bharat Rashtra Samithi (BRS), according to party insiders, is also not going to attend the event but it has not issued an official statement yet.

Here is how the 19 parties that issued the joint statement and the AIMIM are placed in Parliament at the moment:

All these parties fall short of the strength of the BJP in the Lok Sabha where the ruling party has 301 members. In the Rajya Sabha, they are just four seats more than the BJP that has 93 MPs in the Upper House. But, the BJP can count on the support of smaller National Democratic Alliance (NDA) members and parties such as the YSR Congress Party (YSRCP) and the Biju Janata Dal (BJD), both of which will attend the inauguration of the new Parliament building. With their support — the YSRCP has 23 Upper House MPs and the BJD nine — the BJP is comfortably placed in the Rajya Sabha too.
