Water woes in Pune further strained relations between BJP and its ally Shiv Sena as the latter today launched a signature campaign to oppose District Guardian Minister Girish Bapat's decision to release water from Khadakwasla dam to adjacent Daund and Indapur talukas.

Joining the anti-Bapat campaign already launched by other parties, including NCP, MNS and Congress, Shiv Sena city president Vinayak Nimhan said the memorandum accompanying citizen's signatures, being collected by activists at various public places, would be sent to Chief Minister Devendra Fadnavis to oppose the "arbitrary" decision of the minister.
