A three-member Trinamool Congress parliamentary delagation would visit Rajkot and Una tomorrow.
"After raising the issue in Parliament, now it is time to further assess the situation on the ground and meet those affected," Derek O'Brien, TMC chief national spokesperson said.
Apart from Derek, who is the TMC parliamentary party leader in Rajya Sabha, the two other members of the delegation are Kakoli Ghosh Dastidar and Pratima Mandal, Lok Sabha MPs.
Earlier, TMC supremo Mamata Banerjee had called the Una incident an "organised crime" against Dalits.
She also urged the Centre to treat Dalits with care and give full protection to them.
