Actor-turned-politician Shatrughan Sinha, who is contesting from Patna Sahib constituency on a Congress ticket, came under criticism after he campaigned for his wife Poonam Sinha. Poonam recently joined the Samajwadi Party and is Akhilesh Yadav's pick to take on Home minister Rajnath Singh from Lucknow. Notably, Congress and the Mahagathbandhan of the SP, BSP and the RLD are pitted against each other in the crucial battle for 80 seats of Uttar Pradesh. The Congress was initially expected to be part of this alliance but the SP and BSP left only three seats for the party to contest in UP. Shatrughan Sinha, a turncoat who recently jumped ship from the BJP after being critical of the party for a long period, today campaigned for his wife and the Samajwadi Party in Lucknow. A row erupted after Congress\u2019 Lucknow candidate Acharya Pramod Krishnam expressed his displeasure at the development. "Sinha Ji ne yahan aa karke apna pati-dharm nibhaya hai, lekin mai Shatru Ji se ye kehna chahunga ki pati-dharm unhone aaj nibha diya, lekin ek din mere liye prachar karke wo party-dharm nibhayein (Shatrughan Sinha has said he was doing his duty as a husband, I would like to tell him that he has taken care of his husband duties but now he should campaign for me and do his duty for the party.) Rival parties It is interesting to note that Sinha was present when his wife Poonam filed her nomination for the Lok Sabha polls today. The situation is not a problem as both are contesting from different places and different states. However, the campaigning by the Bollywood veteran has irked Poonam Sinha\u2019s Congress rival Acharya Pramod Krishnam.
