"It is shocking ... the Delhi government should institute a high-level inquiry into the collapse", Prasad and Paswan told reporters before leaving for campaigning.
They also demanded an ex-gratia payment of Rs 20 lakh to bereaved families of each of the deceased and free treatment and compensation for the injured.
Prasad also demanded that a case of murder be registered against the builder.
