NEW DELHI: Amid dissidence in Punjab unit, Congress member Manish Tewari said Congress is its own enemy and infighting was the cause of defeats, even as he asked party men to fight Punjab polls unitedly. The upfront comments triggered a buzz that Tewari could be appointed as the state president as part of the reorganisation that is to be announced soon. “In my 40 years in the party, I’ve seen that nobody defeats Congress and Congress defeats itself,” he said. In a jibe at dissident Navjot Singh Sidhu, Tewari, who is among top contenders for post of Punjab chief as a nominee of CM Amarinder Singh, said, “The party in the state is united. But if somebody is running an agenda on Twitter, party leadership should take a serious note of it.”
