Unfazed by the desertion of key allies PMK, RJD, LJP and SP, Congress on Friday expressed confidence that they would come back to the UPA after the polls, saying they continue to affirm their faith in prime minister Manmohan Singh and Congress president Sonia Gandhi.

"They have not expressed lack of confidence in PM Manmohan Singh and Congress president Sonia Gandhi...This is electoral politics and political parties have their own
positions," party spokesman Anand Sharma told reporters here.

Sharma said "sometimes there are disagreements" but complimented these parties saying they have expressed faith in the leadership of the PM and Congress president. He said that even in the 2004 elections, the allies came to the UPA after the polls and claimed the Congress was not worried on this count.

Asked whether the party hoped of coming to power on its own after the elections, Sharma said the Congress would improve substantially and was confident to form the next government.

"Post poll, government formation is purely a game of numbers. After the elections, post alliance will take place," he said.
