"RLD's decision was a sort of surprise but we are ready with the numbers and confident of winning the trust vote," Prithviraj Chavan, Minister of state in the PMO, said here.

Chavan claimed "surprises" would be there as the Congress has a "cushion" of support from parties other than the UPA partners.

"Surprises would happen at the last minute. A lot of work has gone into it," the Congress leader said.

Chavan claimed that more than four BJP MPs are in touch with the Congress apart from some from the Shiv Sena. He, however, refused to give the names.

Asked how many Congress MPs would desert the party before the trial of strength, Chavan said he did not expect any Congress MP to vote against the Government except those who have already come out openly.

"I do not expect any Congress MP to leave unless defeat is staring in the face and that is not the case here," he said.

In reply to another question on the reducing numbers of the Samajwadi Party, Chavan said SP has assured the Congress of a specific number and that remains almost intact.
