The 65-year-old leader's ascent as the DMK chief heralds a new era in the Dravidian party, making him only the second man after his father to be elected as party president.
If the DMK under Stalin is unable to do well in the Lok Sabha elections, his personal and political standing in the party will be threatened. But if the party does well, Stalin is the next kingmaker to watch out for. T E Narasimhan and Aditi Phadnis report.
If either faction of the AIADMK failed to muster a floor majority, then the governor would be called upon to ask MK Stalin as the leader of the opposition if he would like to try his hand at government formation.
The 65-year-old Stalin's elevation comes about three weeks after the death of his father and party president M Karunanidhi.
M K Stalin might not have his father's charisma, but he has learnt the ropes the long, hard way, says T E Narasimhan
Stalin has given due respect to seniority in the pecking order, but has also taken into consideration the demands of individual ministries and the suitability of individuals, observes N Sathiya Moorthy.
