Union Finance Minister Arun Jaitley believes that preparations for the 1975 Emergency had been made as early as six months before it was actually imposed.

In the second part of his Facebook post released today, Jaitley asked, "Was the script of Emergency prepared in advance?"

He said journalist Coomi Kapoor's book on the Emergency, published in 2015, contains documents in the writing of Siddhartha Shankar Ray where he requests the then prime minister Indira Gandhi to have lists of persons proposed to be arrested ready and outlines various other steps which were required to be taken.

The document is dated January 8, 1975, he said.
