Taking a swipe at Maharashtra Chief Minister Devendra Fadnavis over his "remote control" remarks, ally Shiv Sena today said he should concentrate first on "charging the batteries" of his political will to fight the threat posed by ISIS in the state.

Fadnavis, while speaking at an event to commemorate Bal Thackeray¿s birth anniversary here, had recently said that the late Sena Supremo may have given Uddhav Thackeray the remote control of power, but he has in turn handed it over to him.
