"We condemn the imposition of President's rule there (Arunachal Pradesh). It is an anti-constitutional step by the NDA government. We demand withdrawal of the decision and recall of Rajkhowa in the interest of democracy," CPI general secretary S Sudhakar Reddy said in a statement.
Reddy also targeted Rajkhowa for allegedly taking "over-initiative" in helping BJP impose central rule in the north-eastern state.
He dismissed the Governor's reported remarks that there was law and order problem in the state (before the central rule was clamped).
Arunachal Pradesh came under central rule after President Pranab Mukherjee gave assent to the Union Cabinet's recommendation on such a course following political instability in the state on January 26.
The state has been rocked by a political crisis since December 16 last year when 21 rebel Congress MLAs joined hands with 11 of BJP and two independents to 'impeach' Assembly Speaker Nabam Rebia at a makeshift venue. Rebia had branded the move as "illegal and unconstitutional".
