Enraged with Dayashankar Singh Singh's derogatory remark against Mayawati, Bahujan Samajwadi Party (BSP) workers staged a protest here on Thursday morning, demanding the arrest of suspended BJP state vice president. The protest is being held at the main Hazratganj crossing. BSP state president Ram Achal Rajbhar said that the party supporters have been asked to gather in the state capital in larger numbers. Meanwhile, the BJP has expelled Dayashankar Singh from the party for six years.
