Talks between People’s Welfare Alliance and DMDK seems to be progressing smoothly but alliance is yet to be firmed up. According to PWA sources, front’s coordinator and MDMK general secretary Vaiko met Vijayakanth’s wife Premalatha and his brother-in-law L.K. Sudeesh on Monday late evening to discuss modalities of alliance. The meeting took place on the same day when DMK chief M. Karunanidhi claimed that alliance talks between DMK and DMDK were on.
