"One dictator, autocrat, with a self-serving image (of the leader) has started the beginning of the end of BJP", party spokesman Abhishek Singhvi told reporters here.
He said that this was not being stated by Congress leaders alone but many in BJP too.
The spokesman was reacting to a question on the poll jingle brought out by BJP showing Modi as a strong and decisive leader who will not allow the country's interests to be compromised at any cost.
Singhvi also rejected the BJP charge that the government is not allowing Modi to address rallies, saying that it has given full freedom to everyone to go to every nook and corner and continue with his "false propaganda".
Turning to the 2002 Gujarat riots, he said, "Let him (Modi) make a statement reflecting even a skeleton of an apology, forget an apology."
He sought to take the wind out of BJP's good governance and development plank by trotting out figures showing NDA in poor light.
"These are the supreme ironies from which the BJP and Narendra Modi are running away. People can lie and distort, but facts cannot be ignored. Rhetorics, polemics, slogans, supposed oratory skills or as we are now told lack of oratory skills will not make up for facts.
"Competition for good governance can be only between UPA-I and UPA-II and not between UPA and NDA. You cannot substitute facts by hurling abuses in rallies and making taunts", he said, adding that while Congress has walked the talk, BJP is trying to fool the people with slogans.
Citing figures of growth in agriculture, industry and services, Singhvi claimed that NDA was a "laggard" and UPA-I did better than UPA-II. "Even the worst performance of UPA is better than the best performance of NDA."
He said the GDP growth which was six per cent in the six years of NDA rule rose to 8.4 per cent during UPA-I and it was 7.3 per cent in the first two years of UPA-II, "our lower and worst".
He said the agricultre growth rate was just 2.9 per cent during NDA rule while it was 3.91 in UPA-I and 3.6 in the two years of UPA-II.
"The growth in services sector was 7.8 per cent in NDA, 9.9 per cent in UPA-I and 8.9 per cent in UPA-II. Even in fiscal deficit, the 5.5 per cent in NDA was matched by UPA-II," Singhvi said.
He also claimed that UPA achieved significantly in poverty reduction.
