NEW DELHI: West Bengal chief minister Mamata Banerjee-headed Trinamool Congress (TMC) breaking ranks with the opposition in the vice-presidential election remains a mystery but the party had, in fact, started parting ways with the Congress-led UPA in the presidential poll itself.
The chronology of events relating to both the recently-concluded presidential election and the August 6 vice-presidential poll makes it clear that Banerjee had started making up her mind to split with the opposition parties at the start of this month.
