Amid speculation that Congress and DMK have sorted out their differences over cabinet berths to pave the way for the regional party to join the UPA government, Chief Minister M Karunanidhi's son M K Azhagiri, who is tipped to become a cabinet minister today left for New Delhi.

Azhagiri's departure, along with his family members and some supporters, comes in the wake of report that his party worked out a formula with Congress under which the DMK would be provided with three cabinet berths.
