"We will submit signature of one crore people of Odisha in support of the special category status to the President of India," Patnaik told reporters on his return from a five-day visit to the national capital.
Stating that the ruling BJD has planned a mass congregation at Ramlila Maidan in Delhi on June 12 to press for the demand, Patnaik said he had already raised the issue with the Planning Commission during a discussion on plan size determination on June 4.
The BJD's rally would follow Bihar Chief Minister Nitish Kumar's 'Adhikar' rally demanding special category state status for his state.
Odisha's rally will mark the culmination of the ruling BJD's months long campaign launched on April 28 for special category state status.
Earlier last month, Ahluwalia had rejected Odisha's plea for SCS, saying the state did not qualify for it under the existing criteria.
