New Delhi: Asserting that the demand for dissolution of the Uttar Pradesh Assembly should not be accepted, CPM (Communist Party of India-Marxist) on August 26 said it was incumbent on the Uttar Pradesh Governor to call Samajwadi Party to form government in the wake of the "collapse" of the Mayawati government.

"Democratic norms demand that the leader of the single largest party in the Assembly, the Samajwadi Party, be asked to form the government," the party Polit Bureau said in a statement in New Delhi.

The party said it was now incumbent upon the Governor to explore the possibility of the formation of an alternative government and the new government should be asked to prove its majority in the Assembly.

"The demand for dissolution of the Assembly or the imposition of President's rule cannot be accepted," it said.
