Shiv Sena leader Sanjay Raut said that the seat sharing with BJP is a tougher task than India-Pakistan partition. BJP, Shiv Sena leaders have been holding meetings to finalise the seat-sharing agreement for the upcoming Maharashtra Assembly polls. The BJP-Shiv Sena seat sharing formula is likely to be announced soon even as Shiv Sena has been insisting on 50:50 seat sharing agreement. Assembly elections in Maharashtra are slated to be held on October 21.
