Actor-turned-politician Shatrughan Sinha today officially joined the Congress, on the Sansthapna Diwas or Foundation Day of his outgoing party, the BJP. As he bid a farewell to the BJP, with which he has shared an acrimonious relationship for years, the lawmaker took pot shots at Prime Minister Narendra Modi and party chief Amit Shah. "In the one-man show, two-man army, everything happens from Prime Minister's Office... the ministers can't work freely anyway," he said.
