In a shocking development, the president of Nationalist Congress Party's Mumbai chief and former minister Sachin Ahir joined the Shiv Sena on Thursday morning.

Ahir has been leading city NCP for a couple of years and worked in the position in the past as well. He was a minister of state in erstwhile Congress-NCP governments. His fall-out with Sharad Pawar-led party is seen as the result of a sense of insecurity in the opposition camp.
