Karnataka Chief Minister HD Kumaraswamy, moving a motion for a trust vote, said today that his government had faced many hurdles but he was confident of winning the test of strength. The Congress-Janata Dal Secular coalition is on the verge of collapse after the resignation of 16 legislators and two independents pulling their support earlier this month. A prominent Congress rebel, Ramalinga Reddy, was present in the house, indicating that he was back in the fold, but it doesn't make any difference to the coalition's precarious position.
