Prime Minister Narendra Modi on Sunday attacked the Congress, accusing that its 'shahi parivar' (royal family) is hell bent on breaking the ST-SC-OBC unity to "snatch reservations under an evil design". Addressing an election rally at Gumla, he accused the JMM-led coalition of looting the state's rich resources such as minerals, forest, sand and coal, putting 'roti-beti-mati' (bread, land and daughter) at a grave threat. He also accused the ruling state government of fuelling illegal immigration.
