Pramod Sawant of the BJP has reached the party office in Goa as the votes are counted in the coastal state.
In images, Mr. Sawant was seen praying at the BJP office.
The party has said it has confidence in the support of the regional Maharashtrawadi Gomantak Party, or MGP, as both sides are “ideologically aligned”.
Ties between the BJP and the MGP had soured in 2019 when two MGP ministers were fired from the state cabinet led by Mr Sawant.
Most exit polls have predicted a hanged house in Goa, leading political parties to develop strategies that consider different scenarios after the outcome.
