"If a Government is formed, it will always either be BJP-led or Congress-led," Advani said.
He added, "If Communist parties think the Third Front will come to power, then they are wrong."
He raised concern over the threat from the growing power of Taliban in the neighbouring country and said UPA government was incompetent to deal with terrorism.
"Threat from the Taliban is just 20 km away from the Indian border but this government is just not capable of fighting terror. There have been so many terrorist attacks in the country over the last five years and hardly any terrorist has been caught," he said.
The region will go into polling on May 7, for the fourth phase of the general elections.
