Following MGPs victory in the first election, the MGP demanded that Goa be merged into Maharashtra. The MGP wanted that the issue should be voted in the Goa legislature, as was the norm in a representative democracy. The UGP was of the opinion that such an important decision should not be left to them MLAs but should be put before the people of Goa to decide. If the merger was to be voted in the Goa legislature, it was a foregone conclusion that the MGP with its majority would push through the merger. The UGP MLAs visited New Delhi several times to convince them to hold a referendum in Goa. First they met
Jawaharlal Nehru; and after his death, met
Lal Bahadur Shastri to press for a referendum. However Shastri died in 1966 in
Tashkent and this decision was now left to the new prime minister
Indira Gandhi. The UGP delegation met her and submitted a memorandum that such a monumental decision affecting the future of the State could not be left to legislators alone, but should be put before the people to decide. Finally the central government agreed to
hold a referendum in Goa. The UGP demanded that all people from Goa, regardless of where they were staying in India, should be allowed to vote. Those staying outside Goa could vote by postal ballot. However this request was denied. They also demanded that all deputationinsts from Maharashtra should not be allowed to vote and that the Bandodkar ministry should resign to conduct a free and fair poll. The centre conceded the demand for Bandodkar's resignation. The
opinion poll was held on 16 January 1967. A total of 3,17,633 votes were polled. The merger was defeated by 34,021 votes. ==First split==
