We will not shy away from our responsibility, says BJP leader P Muralidhar Rao. (File)

A Bharatiya Janata Party (BJP) government is expected to take charge in Karnataka next week, party national general secretary P Muralidhar Rao claimed today.

He said the BJP was confident that the Congress-JDS government, led by Chief Minister HD Kumaraswamy, would lose the trust vote in the Legislative Assembly on Thursday.

"You can expect," Mr Rao said when asked if a BJP government is expected to be in place in Karnataka next week. "We will not shy away from our responsibility," he added.

The coalition government is in "clear minority" and should go, Mr Rao said.

The Supreme Court earlier today directed that the 15 rebel Congress and JD(S) MLAs "ought not" to be compelled to take part in the proceedings of the Assembly, which is slated to decide a confidence motion moved by the state government on Thursday.

It said Assembly Speaker KR Ramesh Kumar was free to decide on the resignations of the rebel legislators within such time-frame as deemed appropriate by him.

Welcoming the court's direction, Mr Rao said the speaker cannot be "arbitrary" and should take a decision within a reasonable time-frame.

"Since now he (the speaker) has gone beyond a point, at least at this point, there should not be a compelling whip to participate. So, in a way, the Supreme Court while accepting speaker''s domain, has created a situation where these MLAs should not be compelled to attend the trust vote. So, whip should not be the factor," he said.

"So, the Supreme Court in a way has given protection to 15 MLAs while exercising their right. Now, in my view, disqualification (of rebel MLAs) is not possible," he added.

"The way Supreme Court has given the direction, it is in a way, a guideline for the speaker for the future," Mr Rao said.
