Why opposition calls for non-BJP Speaker in Lok Sabha, as TDP and JD(U) clamour for post

The first session of the 18th Lok Sabha is underway amidst opposition protest against the appointment of seven-time BJP MP Bhartruhari Mahtab as the Pro-Tem Speaker.

The senior most member of parliament is traditionally appointed Pro-Tem Speaker. Opposition argues that Kodikunnil Suresh, eight-time MP from Kerala and a Dalit leader, should have been appointed to the post.

But all eyes are on July 26 when Lok Sabha members will elect the Speaker, who will conduct the House for the rest of the term. Telugu Desam Party (TDP) and Janata Dal United (JDU) -- both members of the ruling National Democratic Alliance (NDA) -- are vying for the post, but the Bharatiya Janata Party (BJP), the biggest bloc in the alliance, does not want to give it away.

From conducting the House and allowing questions to disqualification of members and presiding over trust votes, the Speaker holds vast powers in the Lower House.

Here's a close look at those powers and why the post is crucial for BJP, its allies and even the opposition in the Lok Sabha.
