JSS and CMP, too, have issues with the Congress as they think their parties are being sidelined by the 'big brother attitude of the Congress'.
The SJD, led by media honcho M.P.Veerendra Kumar, is expected to raise the demand for a Lok Sabha seat.
It is not clear if the allies will also discuss issues like the 'solar scam' and the recent gold haul at Kochi airport, which they claim have dented the image of the CM's office.
The differences between the Chandy and Ramesh Chennithala factions in the Congress party are also likely to come up at the meeting with Sonia Gandhi.
