The assurance comes after some senior leaders, including legislator Aleixo Reginaldo Lourenco, had claimed yesterday that the party was not taken into confidence before some leaders committed to being part of the delegation.
The Congress, after a meeting today, authorised the Leader of Opposition Chandrakant Kavlekar and legislator Nilkant Halarnkar to be part of the delegation to Delhi.
"The Congress Legislative Party is of the firm view that the party should do everything possible to protect the livelihood of nearly two lakh people who are dependent on the mining business, directly or indirectly," Kavlekar told reporters after the meeting.
In a recent order the Supreme Court had quashed 88 mining leases in the state and had also banned the extraction of iron ore from March 15.
A meeting attended by representatives of all parties, chaired by Transport Minister Sudin Dhavalikar, on March 1 had decided to send an all party delegation to Delhi to meet Union Shipping Minister Nitin Gadkari and Union mines minister Narendra Singh Tomar.
