Chandigarh: BJP-SAD alliance has managed a clean sweep of all the three posts in the mayoral elections, putting an end on the eight-year-long winning streak of opposition Congress. BJP councillor Arun Sood defeated Mukesh Bassi of the Congress by a margin of 6 votes for the post of mayor. For the post of senior deputy mayor, Davesh Moudgil got 23 votes while Congress candidate Darshan Garg could manage only 13 of them and for the post of deputy mayor, Hardeep Singh of SAD polled 21 votes, defeating Gurbax Rawat of the Congress. “Congress was thinking that differences within the BJP will make them win the elections easily but they were mistaken. I would just like to say united we stand, divided we fall,” said BJP leader and former MP Satya Pal Jain who was present during the elections. According to sources, in the mayor polling, five of the nine votes of the nominated councillors are said to have been cast for the BJP.
