AIADMK coordinator O Panneerselvam was responding to reporters' queries on the DMK filing graft complaints against ruling party leaders, including him and Chief Minister K Palaniswami.
"These are baseless charges. We will face the charges in court with proper evidence and defeat them (DMK)," he said.
The DMK has filed complaints alleging corruption against Palaniswami, Panneerselvam and Local Administration Minister S P Velumani with the Directorate of Vigilance and Anti Corruption and also moved the Madras High Court, alleging inaction by the vigilance.
The opposition party had Monday filed a complaint against Electricity Minister P Thangamani, alleging corruption in purchase of coal and wind power.
