The Bharatiya Janata Party (BJP) leader also questioned the huge cost being incurred on the Congress' campaign much ahead of the Lok Sabha polls.
"The normal practice has been that with the filing of nomination papers, advertisement starts and picks up during the two weeks permitted for campaigning," said Jaitley, the leader of opposition in the Rajya Sabha.
It is "obvious" Congress has a "huge budget for advertising, if advertising is spread over four months", he alleged.
Calling it an image building exercise for Gandhi, Jaitley took a jibe at him saying: "Advertising can market a marketable product, not otherwise."
