Bhaksar Ghose's memory seems to be failing. The attack on Rajvi Gandhi by the Sri Lankan soldier occured in 1987 when he had gone to Colombo to sign the historic Indo-Sri Lankan Peace Agreement under which IPKF troops were deployed in that country's North-East. It was not a useless trip as Ghose wants us to believe but a very signficant one, since it set the stage for Rajiv's assassination four years later.
The IPKF was withdrawn in 1990 during the V.P. Singh government.
As for his comments about T.N. Seshan I could not agree more.
