Bypolls to four vacant Lok Sabha seats, including Ghazipur in Uttar Pradesh, are unlikely to be held, sources said on Monday. The Election Commission and the Legislative Department in the Union Law Ministry are learnt to be in touch with each other on the issue, they said. According to statutory provisions, the Legislative Department has to concur with the EC on delaying or not holding an election or a by-election. The four vacant Lok Sabha seats are Chandrapur and Pune in Maharashtra, Ghazipur in Uttar Pradesh and Ambala in Haryana. Electoral law stipulates that a bypoll has to be held within six months of a seat falling vacant. But the poll panel, based on certain facts, can decide either not to hold or postpone the electoral exercise.
