Tamil Nadu ministers are a bit nervous these days. Not without reason: Chief Minister M K Stalin has been quietly keeping tabs on his ministers’ performances via two organisations. One is the government Intelligence Wing and second, is Peninsula Consultancy. Both these organisations have been secretly monitoring the performances of all the cabinet ministers. The performance appraisal of the ministers will be based on the inputs of both these organisations. So clearly, some heads are going to roll and some may get additional portfolios. For instance, education minister Anbil Mahesh Poyyamozhi heads the list of good performers followed by industries minister Thangam Thennarasu in second place and MSME minister T M Anbarasan in third place. Those who did not perform well are housing minister S Muthuswamy. It was no surprise that the old war horse Durai Murugan also figures in the non-performers list. Meanwhile, Stalin is besieged with another problem. The finance minister P Thiaga Rajan’s private conversation about money allegedly made by his son Udhayanidhi and son-in-law V Sabareesan has put his party in an awkward position. Tamil Nadu BJP chief K Annamalai who earlier exposed corruption of the DMK government is going to town with this new audio tape. So now, there are talks that PTR may be replaced and several names are doing rounds including that of industries minister Thennarasu.
