BJP leader Shatrughan Sinha today called on RJD president Lalu Prasad at Ranchi and described the jailed former Bihar chief minister as the "most popular son of soil" and a "mass leader". The actor-turned-politician, who represents the Patna Sahib constituency in the Lok Sabha, met the RJD supremo on a day the latter was sentenced to 14 years in prison in a fodder scam case.
