"Snooping on the girl was done on behest of "Saheb" not only inside but outside Gujrat also. An all-India inquiry was a genuine need," party General Secretary Shakeel Ahmed Tweeted.
Sometime back, Congress had held a press conference in AICC playing out an audio clip that carried a purported conversation between Modi's close aide Amit Shah and "Saheb" about the snooping details, claiming that "Saheb" in this case was Modi.
Congress has rejected BJP's charge of political vendetta.
BJP had yesterday strongly reacted to the Union Cabinet's decision approving setting up of a judicial Commission of Inquiry to probe charges of spying on a young woman in 2009 allegedly at the behest of Modi.
As BJP alleged that the Centre's move was an attack on the federal structure, Congress spokesperson Abhishek Singhvi had yesterday accused the opposition party of "creating an obfuscation", saying that Modi was involved in "cheap abuse" of power in the case and that the Centre was well within its rights to set up the inquiry commission.
Some Congress leaders also said that that the inquiry should have been ordered earlier with Union Minister Beni Prasad Verma going to the extent of maintaining, "Modi would have been in jail" had the probe started earlier.
