Mamata Banerjee's ministers, who met with her in Kolkata this evening, said that though they are ready to resign if forced, they plan to stick with the UPA. The estrangement between Ms Banerjee and the Congress, with who she partners in her state and at the Centre, has been provoked by her insistence that former President APJ Abdul Kalam is the right and only choice for President of India. The Congress, backed by other allies, has declared Finance Minister Pranab Mukherjee as its candidate.
