"The Gujarati edition of the book written jointly by Narendra Modi and (RSS leader) Rajabhai Nene on L M Inamdar, popularly known as "Vakilsaheb", would be released on Friday," said Rajubhai Dhruv, BJP spokesperson.
Senior RSS leader Bhaiyyaji Joshi and Gujarat Chief Minister Vijay Rupani would be present for the function, he said.
Hindi edition of the book was published two years ago.
Born at Satara in Maharashtra, Inamdar was jailed for eight months during the freedom struggle.
He became RSS pracharak in 1942 and handled various responsibilities in the saffron organisation. He is considered to be Modi's mentor.
