Mumbai, Mar 30 (ANI): Bollywood actor Sonakshi Sinha on her father joining Congress party said, "It is his choice. I think if you are not happy somewhere with how things are functioning, then you must bring a change. That's what he did. I hope with his new association Congress he will be able to do more good work and not feel suppressed. Being a party member from beginning, from time of JP Narayan ji, Atal ji and Advani ji my father has a lot of respect within party and I feel the entire group hasn't been given the respect they deserve. I think he has done it a bit too late, should've done it long back." Shatrughan Sinha has said that he will join Congress in April and he is expected to contest from Patna Sahib Parliamentary seat against Law and Justice Minister Ravi Shankar Prasad.
