Congress-Trinamool ties at breakpoint?

If the confrontation between the Congress and the Trinamool was confined to Kolkata, it could be dismissed as routine. But the face-off between the two allies is now threatening to engulf New Delhi. Trouble erupted over Mamata Banerjee's plan to rename Indira Bhavan. Congress protests over paddy procurement added fuel to the fire. Mamata called the Congress the CPMs B-team. The Congress returned the compliment. The fracas has now turned so ugly, everyone is wondering who is going to pull out of the alliance first.
