Was Lal Bahadur Shastri about to meet Netaji in 1966?

Skeletons continue to tumble after the declassification of 64 Netaji files. In a fresh development, late PM Lal Bahadur Shastri’s son Sunil Shastri claims that 40 minutes before his death on Jan 11, 1966, Shastriji had called the family from Tashkent and said he was going to meet a Special Person and that would be a Great News for India. Was it Netaji Subhas Chandra Bose?
