Demanding that the cow be declared as "mother of the nation", Bharatiya Gau Kranti Manch on Saturday said that a nation-wide mass movement will be launched at Ramlila Maidan on Sunday.

Gopal Mani ji Maharaj, who is founder of the manch, demanded that the Centre should declare cow as "mother of the nation" and a separate ministry for the welfare of cows should also be set up.

"We have been demanding for several years that cow be declared as 'Rashtra Mata’ as we do not see cow as animal. A nation-wide mass movement will be launched at Ramilla Maidan wherein thousands of people will participate," Gopal told reporters here.

He said that they will also request state governments to pay heed to their demands.
