A political controversy has emerged in Chennai following the discovery of an advertisement displayed inside a Chennai Metro train. The advertisement, which promotes a financial service or product, features the slogan 'girlfriend gives 0% interest.' The phrasing has been criticized for being objectifying and inappropriate for public transit.

DMK Member of Parliament Thamizhachi Thangapandian brought the matter to public attention by sharing a photograph of the advertisement on social media. In her post, she expressed strong disapproval of the content and demanded that the authorities responsible for the Chennai Metro Rail Limited (CMRL) take immediate action. She questioned the vetting process that allowed such a message to be displayed in a public space used by commuters of all ages.

While the MP has called for the removal of the ad and accountability for those who approved it, the specific company behind the advertisement has not yet issued a public statement. The incident has sparked a broader conversation regarding the standards and oversight mechanisms for advertisements placed within public infrastructure. As of now, it remains unclear whether the Chennai Metro authorities have officially responded to the demand for the ad's removal or if they have launched an internal review into their advertising approval policies.
