The Aam Aadmi Party (AAP) today alleged that the SAD-BJP government had allocated sand mines for five years instead of three to maintain its control over the mining business even after its “defeat” in the elections.Dinesh Chadha, co-convener of AAP’s RTI wing, said in a statement that documents obtained under the RTI stated that the government recently allocated 90 mines in eight districts for five years till 2021, contrary to the policy of allocating mines for three years.He questioned why at its fag-end, the government had increased the tenure. “It shows that the ruling alliance wants to continue its monopoly over the mining business,” he said, adding if voted to power, AAP would investigate such irregularities.
