Aam Aadmi Party (AAP) leader Kumar Vishwas will address a "Janviswas Rally" in Congress vice president Rahul Gandhi's parliamentary constituency of Amethi on Sunday.
Speaking ahead of the event on Saturday, Vishwas said that he expected it to be disrupted by activists of other political parties, including possibly the Congress and the Samajwadi Party.
On Saturday, a man, identified later as Saif Jafari, threw an egg in the direction of Vishwas and waived a paper stating that the latter had hurt religious sentiments of both majority and minority communities and it "will not be tolerated".
Jafari, a native of Bijnore, was later nabbed by AAP workers and handed over to the police.
Vishwas described the incident as a political conspiracy of opposition parties which feel threatened by the growing popularity of the AAP.
"If these (opposition) political parties think that by throwing eggs, inks, organising attacks they can win elections they should better look towards Delhi," he said.
Vishwas was addressing the press conference after presiding over a function in which over 2000 traders joined the AAP in Lucknow.
Even though the AAP will release its first list of candidates for the 2014 general elections after January 15, party sources said Vishwas is most likely to contest from Amethi.
