He comes from a political lineage famous in the south of Tamil Nadu. Palanivel Thiaga Rajan or PTR, the finance minister in MK Stalin’s cabinet, is the weapon the DMK government will be using to take a hard look at the Centre’s financial policies. The suave former investment banker has been told to deconstruct BJP top brass moves in finance and take them down whenever the opportunity arises. The finance minister’s contempt for the Goa transport minister Mauvin Godinho, who attended the GST meet and kept parroting lines in support of the Centre, will rate as an all-time classic. Dipping with sarcasm, the TN finance minister had a lot to say about Godinho, which he topped off with the throwaway line that said a lot: “Finally, I sincerely request the [Bharatiya Janata Party], even across the political divide, to impose some minimal quality control on its ‘MLA Acquisition’ procedures. If it had done so, Goa, and the Nation would be saved a lot of pain.” Some might say that sarcasm is the lowest form of art but it is an art form the 55-year-old may have perfected. The DMK has always been short of polished speakers in English who could take on Delhi and it has found a champion now. The finance minister and his vitriol could turn out to be a double-edged sword but right now he has been told to sharpen his skills.
