BENGALURU: With a spring in his step and a broad smile, BS Yediyurappa was sworn in as chief minister of Karnataka for the second time in 14 months on Friday evening. It was his fourth overall, making him only the second CM in the state to achieve the feat.The swearing-in of the 76-year-old Lingayat strongman marked the culmination of 21-day political turmoil in Karnataka , which saw the collapse of the Congress-JD(S) government earlier this week.Not wasting any time, the seven-time MLA from Shikaripura said he would prove his majority in the assembly on Monday. As things stand, BJP enjoys a majority in the House, with the support of 105 party MLAs and one independent. The total strength of the assembly is 225, but three MLAs were disqualified by the speaker on Thursday while the decision on the resignations of 14 other rebels is pending, bringing down the effective strength to 208.Among the first decisions of BSY as CM was the announcement of a Rs 100-crore loan waiver for weavers besides providing an additional Rs 4,000 each to farmers under the PM Kisan Samman Nidhi Yojana. The amount will be disbursed in the first two instalments of income support to farmers. Congress and JD(S) boycotted the oath claiming BSY had no mandate to form government.
