Maharashtra minister Nitin Raut on Saturday welcomed the letter written by Congress president Sonia Gandhi to Chief Minister Uddhav Thackeray seeking the implementation of certain measures for the welfare of Dalits and tribals.

Addressing a press conference here, Raut said the "revolutionary letter" will act as the guiding factor for the welfare of the SC/ST communities and other backward classes under the Common Minimum Programme of the ruling alliance in the state.
