"New districts were created during BSP regime and named after dalit and OBC icons so that they always remain a source of inspiration for the society," the former Chief Minister said here in a statement.
"But the present SP government has unnecessarily changed names of the districts with new ones that do not have any serious meaning. It is an insult to icons and to the society, and history will never forgive it," she said.
Mayawati said though reports of change in the names of districts were appearing in the media, she did not believe that the SP government would work "with an ill will" and go to the extent of insulting dalit and OBC icons.
"The decision of the SP government is very painful and condemnable. I think that (by doing so) SP supremo Mulayam Singh Yadav and his Chief Minister son Akhilesh have got their names written in black letters in the pages of history," Mayawati said.
"My government never changed the name of any district, instead it created a new district and gave it an inspirational name," she added.
