Senior Congress leader Aleixo Reginaldo Lourenco added that Leader of the Opposition Chandrakant Kavlekar, who was part of the meeting which had agreed on an all party delegation to Delhi, had not taken the Congress into confidence before committing to it.
"Neither the Congress Legislative Party nor the regional Congress committee is aware of this all party delegation. He has not dicussed anything with us. Whatever we have learnt about this delegation is from the media," Lourenco said.
A recent Supreme Court judgment quashed 88 mining leases and also ordered that no fresh extraction of iron ore would be permitted after March 15.
"The all party delegation is just a farce. It is an attempt to allow mining leases to operate by renewing them rather than auctioning them as recommended by the Supreme Court," he said.
He alleged that BJP led government had been systematically finishing the state's mining industry since 2012 in order to protect the interests of a few mining giants.
"It is playing with the livelihood of innocent people who are dependent on this industry," he said.
