The cables, made public by Wikileaks, also said the party faction led by Antony, the Kerala unit President, refused to support Sanjay and questioned his "rapid ascent to a position of power" asking "what sacrifices he has made for the party or the country".
On the Guwahati AICC session and Youth Congress conclave, the cables said, Sanjay was the star attraction and he received top billing as the prime mover behind the organisation's revitalisation and as a national leader second only to his mother Indira Gandhi.
Despite all the fanfare for Sanjay and the Youth Congress, the cables said, US diplomats in Delhi continue to hear and see no evidence that the quality of YC membership "improved measurably".
"Kerala Congress president A K Antony was one of the only leaders to flatly criticise the new Youth Congress and Sanjay. The other key critic was West Bengal Congress leader P R Dasmunsi," it said.
The cable went on to analyse that in the next year, ie 1977, unhappiness among Congressmen and the organisational ineffectiveness will become an increasing problem.
