Criticising Bharatiya Janata Party (BJP) leader Kailash Vijayvargiya for comparing Shatrughan Sinha with a dog, Janata Dal (United) leader KC Tyagi on Monday said that BJP leaders had lost their 'mental stability' after party's dismal show in Bihar polls. "First the Prime Minister's remark on minorities, then VK Singh's remark on Dalits, and now Vijayvargiya ji is comparing his senior party leaders with dog. This is disgraceful, he (Sinha) is a senior party leader and a veteran actor, such statements do not suit a politician," Tyagi told ANI.

"Bihar loss has also affected their mental balance, otherwise they would not have made such remarks against their senior party member," he added.

Vijayvargiya had earlier expressed his disappointment over Shatrughan Sinha's remarks over BJP's dismal performance in the Bihar Assembly polls, comparing him to a dog walking past a car and thinking that the car was following it. Shatrughan Sinha on Sunday said ignoring him in Bihar had cost his party a humiliating defeat. "You removed deserving people. You kept 'Bihari Babu' away from Bihar," Sinha had said. The Mahagathbandhan won 178 seats in Bihar, a commanding two-third majority in the 243-member assembly. The Bharatiya Janata Party and its allies had to settle for a mere 58 seats.
