In a huge victory for the Congress today, the party won the Gurdaspur Lok Sabha by-poll in Punjab by a margin of nearly 2 lakh votes. The seat has been a BJP stronghold and was held by the actor-turned-politician Vinod Khanna since 1998. The by-poll was being seen as a call on the popularity of the six-month old government of Captain Amarinder Singh in the state. Navjot Singh Sidhu, who switched over to the Congress from the BJP ahead of state polls earlier this year, shares his take on the results.
