A formal decision on Hamid Ansari as UPA's candidate for Vice Presidential election is likely to be taken at a meeting of the ruling alliance in New Delhi on Saturday.

A second term for incumbent Ansari appears certain with several parties in the alliance and outside giving their support to his candidature in the August 7 election.

Key UPA constituent Trinamool Congress, however, may propose the name of former West Bengal Governor Gopalkrishna Gandhi as Mamata Banerjee is not quite enthusiastic about Ansari's candidature for second term.

The last day for filing nomination for Vice Presidential election is July 20, a day after the Presidential poll.
