Karnataka Chief Minister HD Kumaraswamy has to prove his government’s majority in the Legislative Assembly on Friday. It will be a real acid test for the Congress-JD(S) alliance. Even, the election to Assembly Speaker and Deputy Speaker will take place today. The BJP decided to field its candidate for the Speaker’s post. The Congress-JD(S) combine has a total tally of 115 while the magic figure is 112 to prove majority. But, DK Shivakumar, who is unhappy for not getting cabinet berth, may spring a surprise.
