BJP MLA Sadhana Singh on Sunday said that BSP chief Mayawati is "a blot on womankind" and is "neither man nor woman". "Mayawati has no self-respect...she was disrobed earlier...but still sold her dignity for the sake of power," she added. Singh's statement was in reference to the 1995 Lucknow guest house incident when Mayawati was allegedly assaulted by SP workers.
