BJP's Devendra Fadnavis today chose to remain tight-lipped on alliance with the Nationalist Congress Party's Ajit Pawar that lasted for just 80 hours before the four-day old BJP government in Maharashtra collapsed on Tuesday. "Sahi waqt pe sahi baat karunga.... chinta mat karo (I will say the right thing at the right time... don't worry)," the 49-year-old BJP leader told reporters this afternoon while replying to a question on whether it was a mistake to forge an alliance with NCP leader Ajit Pawar and form government in the state.
