"Digvijaya Singh is not officially authorized to speak on behalf of the party," said the AICC in a media release.
The statement comes after he called the West Bengal Chief Minister "erratic" and "immature", adding that the party had a limit to its tolerance.
Digvijay Singh in a series of television interviews, said that the Congress party will not go behind a limit to appease Mamata Banerjee.
However, this is not the first time that the Congress has distanced itself from Digvijay Singh's comments.
"All efforts have been made to console her, accept her views, accept her tantrums...Beyond a certain limit, the decision is hers...There is a limit to which you can bend to...There are certain eventualities, which if it cannot be avoided have to be faced," Singh had said.
In an interview with to Karan Thapar on CNN IBN's Devil's Advocate, Digvijay Singh said that the UPA was not showing the exit door to Mamata Banerjee and was not "throwing her out".
He further intensified the row by saying Prime Minister Manmohan Singh and Congress President Sonia Gandhi were embarrassed after she rejected the chosen names for the President's post, but instead joined hands with the Samajwadi Party and announced three other names, including that of Prime Minister Singh when they "did not have consent of any of the three".
