Harish Rawat was considered a strong contender for Uttarakhand CM's job. He was apparently ignored after the Congress chose MP Vijay Bahuguna to be the CM. Ghulam Nabi Azad, Union Minister and Congress leader who is in-charge of forming the government in Uttarakhand said, "It was decided by party MLAs and all leaders that Vijay Bahuguna will be the chief minister."
Supporters of Rawat have gathered outside his residence and shouting slogans against the High Command's decision to choose Bahuguna over Rawat. Ghulam Nabi Azad is understood to be engaged in discussions with Rawat to convince him to withdraw the resignation.
The Prime Minister's office has however denied the reports regarding Rawat's resignation.
More details awaited.
