Ahluwalia said that he advised Mr. Singh to not think about the resign as the issue was not appropriate.
"I was part of the PM's delegation in New York and my brother Sanjeev, who had retired from the IAS, telephoned to say he had written a piece that was very critical of the PM. He had emailed it to me and said he hoped I didn't find it embarrassing," he recalled.
"The first thing I did was to take the text across to the PM's suite because I wanted him to hear about it first from me. He read it in silence and, at first, made no comment. Then, he suddenly asked me whether I thought he should resign," Ahluwalia has written in his new book "Backstage: The Story behind India's High Growth Years".
"I thought about it for a while and said I did not think a resignation on this issue was appropriate. I wondered then whether I was simply saying what I thought he would like to hear but on reflection I am convinced I gave him honest advice," he maintained.
"Congress saw Rahul as the natural leader of the party and wanted him to take a larger role. In this situation, as soon as Rahul expressed his opposition to the ordinance, senior Congress politicians, who had earlier supported the proposed ordinance in the Cabinet and even defended it publicly, promptly changed their position," he added.
