"Giving a live demonstration of electronic voting machines (EVMs) in Delhi by AAP is a disgraceful and irresponsible act," Chugh said in a statement issued here.
During a day-long special sitting of the Delhi Assembly today, AAP MLA Saurabh Bhardwaj put on a "live demonstration" on how EVMs can be programmed to favour any political party.
Stating that the post of chief minister is a constitutional post, Chugh accused Kejriwal of "hatching a conspiracy" to defame the country's electoral process.
Bhardwaj claimed that a voting machine could be manipulated by simply feeding it a "secret code".
