Leaders from 22 opposition parties came together at Mamata Banerjee's mega rally in Kolkata on Saturday.
Karnataka Chief Minister HD Kumaraswamy has said that people of the country were totally "disappointed" with the administration of Prime Minister Narendra Modi and heaped praise on his West Bengal counterpart Mamata Banerjee, saying she is a "good administrator" and has all capabilities of leading the country.
The Janata Dal (Secular) leader, however, maintained that leadership was not the pressing issue at hand and the opposition needs to focus on ways and ideas to win the polls.
In an interview to news agency PTI, the Karnataka chief minister said, "According to me, deciding on the leadership is not a criterion to win the polls. People of the country are totally disappointed with the administration of Narendra Modi. Several states have their own problems. It is not necessary to select a leader before the elections.
"There are effective leaders, who can move in a big way for the development of the country. They can make headway in areas where the previous governments have failed. But we can sit and select our leader after the elections are over," he said.
Mr Kumarswamy, who was part of the Trinamool Congress-led mega opposition rally -- United India Rally -- held in Kolkata on Saturday, also said that Ms Banerjee has the abilities to run the country.
"She (Mamata) is simplest of the simple and a very good administrator. I believe that Mamata ji has all the capabilities of leading the country. And she has already proved herself by leading West Bengal for so many years."
Drawing parallels with the situation the country in 1977 when Prime Minister Indira Gandhi faced revolt from various quarters, Mr Kumaraswamy said, "The present scenario is quite similar to that period. Even the politicians sat together and select their leader. This time, too, I think we will also have no problem in doing that."
The Janata Dal (Secular) leader asserted that the Mahagatbandhan would be "an alternate to the national party".
"Several states have their own problems. Each of them have regional leaders who are as strong as national party members. And these regional parties will play a crucial role in the elections. This time people are going to bless them."
Talking about the absence of Telangana Chief Minister KCR at the mega rally called by Ms Banerjee, Mr Kumaraswamy said, "I think after the elections everybody will join. Everybody will come together. I am quite hopeful."
Incidentally, KCR had came down to Kolkata to meet Ms Banerjee last month for a discussion on the grand alliance. He, however, stated that his efforts for a non-BJP and non-Congress alliance would continue.
Heaping praises on Ms Banerjee for bringing together opposition leaders on a same platform, the Karnataka CM said, "Mamata jidid a great job in organizing the rally. She had even requested the Left to join her. This shows her generosity in her tactics in fighting the BJP government. She is ready to make compromises to take our fight to the next level."
Setting the tone for the Lok Sabha polls, leaders from 22 opposition parties came together at the mega rally in Kolkata on Saturday and declared they will put up a united fight to oust the Narendra Modi government.
