Launching a blistering attack on Narendra Modi, Congress today compared his rallies with circus shows "which also fetch crowd" and questioned his understanding of foreign affairs.

"Do not measure one's strength from one's obesity. Famous filmstar Raj Kumar had once said that a lot clapping is made and a large crowd gathers even when some circus comes in the town," party spokesperson Renuka Chowdhary told reporters.

Ridiculing Modi for his yesterday's assertions in Chennai on foreign policy issues, Chowdhary said that it was "very very bizarre" and that the Gujarat Chief Minister has "no idea of foreign policy, has no clue.

"He will come out in a Rambo style and shoot at everyone. That does not happen in foreign policy," she said.
