NEW DELHI: President Ram Nath Kovind on Wednesday rejected the mercy petition of Nirbhaya convict Akshay Kumar Singh, one of the four convicts in the Nirbhay gang-rape and murder case who has been given a death sentence. Akshay had filed the mercy plea last week. Meanwhile, the Delhi High Court on Wednesday, while disposing of the Centre’s plea in the case, noted that “the convicts cannot be executed separately”.
