New Delhi: Making Congress General Secretary Rahul Gandhi the centre of its attack, BJP on Wednesday said he should be more specific in his comments during the Uttar Pradesh election campaign and clarify what he means by a "model state", mafia-rule and constitutional status to Lokpal.

Without naming Gandhi, BJP spokesperson Rajiv Pratap Rudy said the Congress general secretary has often said that he wants to bring about a change in Uttar Pradesh but has not specified the parameters.

"What would be his parameters? Which is the model state he would like to replicate in Uttar Pradesh? Whether it is Andhra Pradesh, which is burning over Telangana, or Rajasthan where the government is surrounded by controversies? We are not able to get an answer," he said.

The BJP MP maintained that when BJP talks about development, it refers to states like Chhattisgarh, Gujarat, Madhya Pradesh and Bihar where it is in power and has been successful.

Upping the ante, Rudy said to learn about development the Congress leader visits the homes of "Lilavatis, Kalavatis" but the BJP would like to know where one has to go to understand corruption.

"There have been no comments from him on this. We have definitely not heard from him on this. We are not able to understand why," Rudy said.

The Rajya Sabha MP also maintained that Gandhi should explain what he means by giving Constitutional status to Lokpal. "CAG is also a constitutional body but its report stating there was Rs 1.76 Lakh Crore loss was declared as just nothing by union minister Kapil Sibal," Rudy said.
