General Secretary Sitaram Yechury Tuesday said allegations against the National Security Adviser (NSA) in the ongoing controversy involving the CBI and also the Rafale deal has raised doubts over the BJP-led government's role in the two cases.

"NSA's name has now surfaced in connection with the CBI fiasco and earlier as the lead negotiator in the corrupt Rafale deal. Is there still any doubt that the strings of the deals do not stop at the NSA but lead directly to his boss?", Yechury tweeted.
