Peoples Democratic Party (PDP) on March 24 unanimously elected her as the legislature party leader.
The real test will now begin for Mehbooba as she has to run the coalition government in which the two allies has many differences. In Kashmir, people are against the alliance as they believe it will pave way for RSS to enter the valley.
While PDP has presently 27 members in the 87-member J&K Assembly, BJP has 25 members.
PDP, which had 28 MLAs prior to the death of Mufti Muhammad Sayeed, claims support of one Independent MLA from Ladakh region while BJP has support of three more MLAs.
The clarity in the formation of the government came after PDP chief met Prime Minister Narendra Modi at his residence in New Delhi few days back.
However, PDP maintained that there are no differences about the portfolios between the two parties.
Sat Sharma said that both the parties have discussed certain issues and finalized the modalities before visiting the Governor with a formal letter of support.
He reiterated the position of his party on the Agenda of Alliance and said that here has been no change in that.
