Allahabad, Nov 28 (ANI): Bharatiya Janata Party (BJP) leader Siddharth Nath Singh on Thursday said Tehelka managing editor Shoma Chaudhury's resignation has come late and added that she should have resigned long time back. He further claimed that Tehelka is a mouthpiece of Congress. Chaudhury has resigned amid unabated criticism for the way she handled a young journalist's complaint that the magazine's founder Tarun Tejpal had molested her in a Goa hotel earlier this month.
