In an U-turn, the Congress today decided to join the all-party committee on uranium mining in Meghalaya. Earlier, the party had decided not to join the committee formed by Chief Minister Donkupar Roy to arrive at a consensus on whether to allow Uranium Corporation of India Limited (UCIL) to go ahead with mining the heavy metal in the state. The decision to join the panel came after the AICC summoned the PCC president O L Nongtdu and Leader of the Opposition D D Lapang to discuss the matter.
