The Third Front was not a threat to UPA, former Karnataka Chief Minister S Bangarappa said on Sunday.
Speaking to reporters in Bangalore, Bangarappa who was admitted to the Congress fold in New Delhi on Saturday, said that the Front was yet to take shape.
BSP leaders Mayawati and AIADMK chief Jayalalitha were not yet committed to join the Front. "So how can you say it has got a headstart", he said.
"I rejoined the Congress to strengthen its secular forces in Karnataka", he said urging secular forces to be united.
Bangarappa had recently resigned from Lok Sabha and state unit presidentship of the Samajwadi Party. An earlier member of Congress, he had been out of it for three years.
