Prime Minister Narendra Modi on Sunday said former Uttar Pradesh chief minister Kalyan Singh was a valuable personality and a capable leader who became a "symbol of faith" for the common people.
PM Modi was speaking to reporters after paying his last respects to the veteran BJP leader at his residence here.
Kalyan Singh died at the Sanjay Gandhi Post Graduate Institute of Medical Sciences (SGPGI) in Lucknow on Saturday night. He was 89.
"The country has lost a valuable personality and a capable leader. To fulfill the void left by him, we should do maximum hard work for his ideals, his promises and leave no effort in achieving his dreams."
The Prime Minister said Kalyan Singh lived his life for the public welfare.
"This is a moment of grief for all of us. His (Kalyan Singh) parents had named him Kalyan Singh. He lived his life in such a way that he fulfilled the name given by his parents. He lived his entire life for the public welfare. He made ''jan kalyan'' as the mantra of his life, and dedicated his life for the BJP, Bharatiya Jan Sangh family, for an ideology and for the bright future of the country," PM Modi said.
He hailed Kalyan Singh as a "committed decision maker" who had become "a name of faith (''vishvaas'') across the country".
"For the most part of his life, he made efforts for public welfare. Whatever responsibility he had got, be it as an MLA, any post in the government, or as a governor, he had been a centre of inspiration for everyone. He became a symbol of faith for the common public," PM Modi added.
"I pray at the feet of Bhagvaan Prabhu Shriram to give Kalyan Singh ji a space at his feet. May Prabhu Ram give strength to his family in the hour of sadness to bear the loss. May Prabhu Ram give consolation to people in the country who believe in his values, ideals, culture and traditions," the prime minister said.
PM Modi, after reaching the residence of Singh here, paid tributes to him and placed a wreath at his body.
He was accompanied by BJP chief JP Nadda, UP Governor Anandiben Patel, UP Chief Minister Yogi Adityanath, deputy chief ministers Keshav Prasad Maurya and Dinesh Sharma.
Defence Minister Rajnath Singh also paid tributes to the former UP chief minister.
Speaking to reporters, Rajnath Singh said, "We used to tell him (Kalyan) that we are ''bhootpoorv'' (former) chief minister, you are ''abhootpoorv'' (unprecedented) chief minister, on which he used to laugh. I have seen him as an elder brother."
BSP chief Mayawati also paid homage to the departed leader.
At around 12.30 pm, Kalyan Singh's body was taken to UP Vidhan Bhavan. From there, it will be taken to the office of the state BJP, party leaders said.
Kalyan Singh, who also served as the Rajasthan governor, was admitted to the Intensive Care Unit of the SGPGI in a critical condition on July 4.
He died due to sepsis and multi-organ failure, the hospital said.
Uttar Pradesh has announced three-day mourning and a holiday on Monday, when the former chief minister's last rites will be performed.
Kalyan Singh was the Uttar Pradesh chief minister when the Babri mosque was demolished by a mob of "karsevaks" in Ayodhya on December 6, 1992. Along with BJP veterans LK Advani and MM Joshi, he was among the 32 people acquitted in the demolition case in September last year.
A Lodhi leader, Singh was instrumental in the rise of the BJP to power in Uttar Pradesh in the 1990s.
He is survived by his wife Ramvati Devi, son Rajveer Singh, who is the Lok Sabha MP from Etah, and grandson Sandeep Singh, who is the minister of state for finance, technical education and medical education in Uttar Pradesh.
