Congress leader Prithviraj Chavan said his party will discuss alliance matters only with Shiv Sena (UBT)'s Uddhav Thackeray and NCP (SP)'s Sharad Pawar amid speculations that Thackeray cousins and NCP factions may join hands. "With whom they (Uddhav Thackeray and Sharad Pawar) do a sub-alliance is entirely their situation," said Chavan. His statement comes ahead of the Maharashtra civic polls.
