Governor Mridula Sinha has convened a special session of the Assembly at 11.30 am Wednesday to enable Chief Minister Pramod Sawant to prove his majority in the House, an official said.
Pramod Sawant will have Narendra Modi’s full backing, but he would have to work out his own ways to reach out to his party men, allies and those sections of Goa voters who would look at the ‘BJP without Manohar Parrikar’ as an anathema.
The BJP-led government in the coastal state claims support of 21 MLAs - 12 from the BJP, three each of allies Goa Forward Party (GFP) and Maharashtrawadi Gomantak Party (MGP) and three Independents.
Sawant visited the family members of Parrikar at their private residence at Dona Paula near here around 12 noon, before heading to the CM's Office at state Secretariat, Porvorim.
Sawant holds a Bachelor's Degree in Ayurveda, Medicine and Surgery and served as the Assembly Speaker before becoming the CM of Goa

The BJP managed to break the deadlock in Goa, offering key allies their pound of flesh, by accepting their demand for deputy CM's posts.

The BJP-led coalition in Goa began discussions on Sunday night to find a new leader to replace Parrikar, who had died earlier in the evening.
Senior BJP leader Nitin Gadkari could not secure consensus between the saffron party and its alliance partners in the state.
Gadkari, who had successfully managed to cobble together a coalition in the state under the leadership of Parrikar in 2017, will be holding discussions with the BJP Goa legislature wing during the night.
While Gadkari was not available for comments, BJP MLA Lobo said Maharashtrawadi Gomantak Party MLA Sudin Dhavalikar wanted to be the chief minister due to which the discussions came to a halt.
