Punjab Congress chief Sunil Jakhar, who lost the Gurdaspur seat to actor-politician Sunny Deol, has stepped down from his post - the latest in a string of several state unit chiefs to resign over the Congress's crushing defeat in the Lok Sabha polls. Though the Congress performance in Punjab has been the best among states, with victories in 8 of the 13 Lok Sabha seats - Mr Jakhar has been unable to retain his seat.
