Kumaraswamy claimed that the BJP has been trying to purchase his MLAs by offering several incentives.
JD(S) MLAs, who had reached Hyderabad in the morning and were staying in Novotel Hotel, left for Bengaluru on Friday night.
The Supreme Court had ordered a floor test in the Karnataka Assembly at 4 PM on Saturday.
The BJP has emerged as the single largest party with 104 seats, followed by the Congress with 78, the JD(S) with 37 and three seats have gone to others in the 224-member assembly where elections were held for 222 seats.
The majority mark is 112 seats and the Congress-JD(S) combine have alleged foul play in the Governor inviting BJP to form the government.
Yeddyurappa, who was sworn in as the Chief Minister of Karnataka yesterday, told the bench that the BJP is the single largest party and has the “mandate of people” of the State who have thrown out the Congress.
In a historic pre-dawn hearing, the top court had yesterday cleared the last-minute hurdle created by the Congress-JD(S) combine for the BJP’s ambitious surge in southern India by paving the way for Yeddyurappa to be sworn in as the chief minister of Karnataka.
