BENGALURU: The BJP government led by B.S. Yeddyurappa faces a crucial trust vote on Saturday in the Karnantaka Assembly that began its new session with MLAs taking oath with numbers stacked against the ruling party on its own.

Governor Vajubhai Vala convened the 15th Karnataka Assembly in the Vidhana Soudha here that began with the newly-elected legislators taking oath. Pro tem Speaker K.G. Bopaiah conducted the proceedings.

Chief Minister B.S. Yeddyurappa was the first to take oath followed by Congress legislature party leader and former Chief Minister Siddaramaiah and Janata Dal-Secular's (JD-S) legislature party leader H.D. Kumaraswamy.

Legislators of the Bharatiya Janata Party, Congress and JD-S were administered the oath in pairs starting with the BJP, followed by that of the Congress and JD-S as per the number of seats they all got in the bitterly fought May 12 election.

Among the prominent legislators present in the House were BJP leaders like former Deputy Chief Minister K.S. Eshwarappa, B. Sreeramulu, Congress legislators D.K. Shivakumar, R.V. Deshpande, M.B. Patil, Shamanuru Shivashankarappa, and JD-S lawmakers G.T. Devegowda and H.D.Revanna.

The oath-taking of all the legislators will be completed before 4 p.m. for Bopaiah to conduct a floor test in the House to ascertain if Yeddyurappa has majority in the hung Assembly, as directed by the Supreme Court on Friday.

If the opposition legislators insist on the division of votes, the pro tem Speaker will ask the members who are in favour of the motion to vote first and those against it soon after.

The May 12 election across the state in 222 constituencies of the 225-member assembly, including one nominated, threw up a hung House, with no party securing majority. The nominated member is yet to be decided and polls in two constituencies were deferred.

Yeddyurappa requires the 112-halfway mark to win the motion or one more than the half of the members present when the floor test is conducted in the House with an effective strength of 222.

Of the 222 seats, the BJP won 104, Congress 78, JD-S, 37 and one each by Bahujan Samaj Party (BSP), Karnataka Pragnyavantha Janatha Party (KPJP) and an Independent.

As the single largest party, the BJP is eight short of the 112-halfway mark in the House.

As Kumaraswamy won from both Channapatna and Ramanagaram segments, the party's effective strength in the House is 36 as he can cast only once.

Though the Governor directed Yeddyurappa to seek a vote of confidence on the floor of the House within 15 days from the date of assumption of office as the Chief Minister (May 17), a three-judge bench of the top court ordered the floor test on Saturday, rejecting his plea for a week's time to prove his majority.
