Senior Congress leader Ashok Chavan on Sunday said that the Shiv Sena was not part of the United Progressive Alliance (UPA) and the tie-up between the two parties is limited to Maharashtra, a day after Sena MP Sanjay Raut called for expansion of the Congress-led bloc.

Speaking to reporters here, the state PWD Minister also said that it was not proper on part of the Sena to comment on the leadership of the UPA.
