Demanding immediate sacking of the minister, Congress workers, led by former MLA and state Congress vice-president Rana KP Singh, raised slogans against Maluka and the SAD-BJP government at the protest in Kansal village.
Congress leaders demanded a CBI probe into the allegations over purchase of school texts and flayed Chief Minister Parkash Singh Badal for shielding the minister.
