Congress President Mallikarjun Kharge announced the name of a united opposition front on July 18 at the end of the 2-day mega conclave.
The coalition will be called Indian National Developmental Inclusive Alliance, Kharge said.
Kharge said that the second meeting of the opposition bloc was a very important one for saving democracy and the Constitution in the interest of the country's people.
"We have come together and discussed various points. With one voice, people supported the resolution adopted today," he said.
"Our alliance will be called Indian National Developmental Inclusive Alliance (INDIA)," Kharge said.
According to multiple sources, the name was suggested by TMC supremo and West Bengal Chief Minister Mamata Banerjee and there was a lot of discussion on the full form of the term, INDIA.
The Congress president said an 11-member coordination committee will be set up and its composition will be finalised in the next meeting in Mumbai. The dates for the Mumbai meeting will be announced soon, he added.
Kharge said a common secretariat will also be set up in Delhi for campaign management and specific committees will be formed for separate issues.
He also launched a scathing attack on Prime Minister Narendra Modi, saying he is now trying to bring together parties that had splintered and this shows that "he is afraid of opposition parties".
"There are some differences between us but we have put that behind... We are together in the interest of the country," Kharge said. "We'll fight the 2024 Lok Sabha elections unitedly and succeed," he said.
In her remarks at the presser, Banerjee, while acknowledging all leaders present, referred to Rahul Gandhi as "our favourite".
Referring to the name of the alliance adopted, Banerjee said, "BJP, can you challenge INDIA? We love our motherland, we are the patriotic people of the country, we are for farmers, Dalits, we are for the country, for the world." The only job the regime at the Centre does today is to buy and sell governments, she alleged.
"INDIA will win, our country will win and BJP will lose," Banerjee said.
