Bollywood actor Sonakshi Sinha on Friday said she supported her father Shatrughan Sinha's decision to quit the Bharatiya Janata Party and join the Congress, adding that her father "should have done it long ago". "I think if you are not happy with how things are going on around you, you should not shy away from change. That's what he did," Ms Sinha was quoted as saying by news agency ANI.
