Karnataka's ruling coalition has time till 1.30 pm today, according to the Governor, to prove its majority in a trust vote that it is almost certain to lose. "You have lost confidence of the house," Governor Vajubhai Vala said in a letter to Chief Minister HD Kumaraswamy, who has been running a Congress-Janata Dal Secular coalition government since May last year. The coalition, which appears to be in a minority after losing the support of 18 lawmakers over the past two weeks, says it is bound to follow only the assembly Speaker.
