Bahujan Samaj Party chief Mayawati on Sunday suspended party's MLA in Madhya Pradesh Rama Bai for supporting the Citizenship (Amendment) Act.
The MLA later claimed that her statement had been "distorted by the media", and sought forgiveness.
Mayawati has been strongly criticising the new law which provides for grant of citizenship to non-Muslim refugees who came to India before December 31, 2014, to escape religious persecution in Pakistan, Bangladesh and Afghanistan.
Rama Bai, who represents Patheriya Assembly seat in Madhya Pradesh's Damoh district, on Saturday evening supported the Act at a function in her constituency in the presence of Union minister Prahlad Patel.
Patel lauded Rama Bai's stand.
Taking a strong note of it, Mayawati, in a tweet on Sunday, said, "The BSP is a disciplined party and it takes prompt action against its MPs and MLAs who break discipline."
