Aiyar was among the first Congress leaders who attacked the Gujarat Chief Minister during the party's election campaign in the state.
Recently, Congress President Arjun Modvadia had compared Chief Minister Narendra Modi to a monkey.
Modvadia, who is the Congress face in Gujarat, without taking Modi's name said that some people have been bitten by dogs and they keep on taking Prime Minister Manmohan Singh's name at regular intervals. He said such people are dreaming of becoming the prime minister of the country.
Modvadia went on to equate Manmohan Singh with a lion and said that a monkey sitting on the top of a tree is trying to challenge the lion while speaking at a rally on Tuesday in Junagarh. He went on to say that a Nobel Prize for telling lies should be constituted and given to Modi. He claimed that Modi had announced packages worth crores for Gujarat but it has not been mentioned in the state budget.
Reacting strongly against the remark on Modi, Gujarat BJP demanded apology from Congress and said, "That is the reason behind Congress using derogatory language against Narendra Modi. Congress is scared of BJP. Congress cannot win a single seat in Gujarat. We demand an immediate apology from Congress for using unparliamentary language against Gujarat Chief Minister."
