Malini Parthasarathy, the first woman editor of Chennai-based Indian daily The Hindu, has quit the newspaper and her resignation has been accepted by the publication.

The reason being speculated for her resignation is the manner in which the Mumbai edition of the 138-year-old English daily was launched last November, especially the expenditure incurred on the edition. The edition was launched on 28 November, 2015.

"We are now truly India's national newspaper, bringing India to Mumbai and Mumbai to India, as only The Hindu can do, given the credibility and integrity of our reporting and the analytic rigour of our coverage," Parthasarathy had written on the occasion of the launch.

Fewer than 40 days later, Parthasarathy has quit. She had taken over as editor of the newspaper on 1 February last year, replacing N Ravi.

"Malini Parthasarathy has tendered her resignation as the editor of The Hindu with immediate effect. After due process, the resignation has been accepted by the board. Until we find a suitable replacement, the national editor of The Hindu, Suresh Nambath, will be taking care of the day-to-day affairs of the paper. An internal communication has been sent to all the employees of The Hindu," N Ram, Chairman of The Hindu's Board of Directors, confirmed to The News Minute.

The Hindu forayed into vernacular news, launching its Tamil edition under the same title and logo, on 17 September, 2013. 

The daily has seen many top-profile exits in the past, including that of Siddharth Varadarajan, who went on to launch a portal, The Wire, along with other journalists.

Malini Parthasarathy's resignation is trending high on Twitter.
