With the Bharatiya Janata Party announcing support to P A Sangma pitting him against UPA Presidential candidate Pranab Mukherjee, the Trinamool Congress said its chief Mamata Banerjee was keeping a close watch and the party would take an 'appropriate decision at the appropriate time'.

"TMC has not taken any final decision as yet. Our party supremo Mamata Banerjee is keeping a close watch on the situation. She will take an appropriate decision at the appropriate time", party MP Kunal Ghosh told PTI without giving a direct reply.

He was asked whether TMC would support Sangma in the Presidential race or abstain from voting since former President A P J Abdul Kalam, whom the TMC supremo wanted to contest, has already opted out.

Ghosh said that the Trinamool Congress parliamentary party and the legislature party has already authorised Mamata Banerjee to take a decision on the Presidential poll issue on behalf of the party.
