"During her campaign against me (Chief Minister) Sheila Dixit would wear onion garlands. Congress made it a big issue.
"The same onion issue is now becoming the cause of the downfall of the Congress government," Swaraj said at the launch here of a book authored by the BJP's prime ministerial candidate for Delhi, Harsha Vardhan.
Rise in the prices of the food item had been one of the major reasons for the downfall in 1998 of the BJP government in the state, then headed by Swaraj.
Meanwhile, Swaraj lashed out at Congress Vice-President Rahul Gandhi for saying that some of the victims of the Muzaffarnagar riots had been approached by Pakistani intelligence agencies.
Swaraj, the Leader of Opposition in Lok Sabha, said that instead of dwelling on violence in Uttar Pradesh, Congress should first speak about the 1984 Delhi riots.
Gandhi, in recent speeches, has attacked BJP for allegedly "spreading hatred", for which the saffron party has filed a complaint with Election Commission claiming violation of the Model Code of Conduct ahead of elections.
Swaraj also slammed Congress for their use of the word "communal", saying the party thought that "by using this word, they can win any election".
Referring to the upcoming Delhi Assembly elections, Swaraj said she would campaign extensively for the same and hold 100 meetings before the city cast its vote on Dec. 4.
"After the Chhattisgarh, Rajasthan and Madhya Pradesh elections, I will devote all the time to Delhi elections," she said.
