Prime Minister Narendra Modi on Sunday said he will be visiting Mumbai later in the day to pay his last respects to legendary singer Lata Mangeshkar.

Mangeshkar, 92, died at a Mumbai hospital on Sunday morning.

"Will be leaving for Mumbai in some time to pay my last respects to Lata Didi," Modi tweeted.

A two-day state mourning will be observed on the demise of the legendary singer on February 6 and 7.

The national flag will fly at half mast on Sunday and Monday throughout India and a state funeral will be accorded to her. 

Earlier, Modi said that Lata Mangeshkar leaves behind a void in the nation that cannot be filled, and the coming generations will remember her as a stalwart of Indian culture whose melodious voice had an unparalleled ability to mesmerise people.

In a tweet, the prime minister said, "I consider it my honour that I have always received immense affection from Lata Didi. My interactions with her will remain unforgettable. I grieve with my fellow Indians on the passing away of Lata Didi. Spoke to her family and expressed condolences. Om Shanti."

Modi said her songs brought out a variety of emotions and she closely witnessed the transitions of the Indian film world for decades.

"Beyond films, she was always passionate about India's growth. She always wanted to see a strong and developed India," he said.
