Industry titan Ratan Tata, who died at the age of 86 in a Mumbai hospital on Wednesday
The national flag will be flown at half-mast across government offices in Maharashtra as a mark of respect.
Ratan Tata's body will be kept at the National Centre for Performing Arts (NCPA) in Mumbai's Nariman Point from 10 am to 4 pm today
Mr Tata's death marks the end of an era in Indian business, where a man reshaped the country's industrial landscape
Although he controlled over 30 companies operating in more than 100 countries across six continents, Mr Tata lived an unassuming life.
Mr Tata's early life was shaped by his exposure to both privilege and hardship. He was raised by his grandmother, Lady Navajbai Tata, after his parents separated when he was a child.
