Questioning Narendra Modi's'certificates' to West Bengal chief minister Mamata Banerjee, Congress on Tuesday wondered if there was a secret "nexus" between the Trinamool Congress and its former ally BJP.
The party pointed to Banerjee "good relations" with the BJP in past and hinted that her arriving in Delhi the same day Modi addressed a meeting in Kolkata could be by "design".
"What is the actual purpose of Modi's visit to Kolkata and why is Mamata Banerjee away? Whatever it may be, we feel there is a nexus between the two parties," WBPCC president Pradip Bhattacharya said in Kolkata.
AICC in-charge for West Bengal Shakeel Ahmed said it was Banerjee or the Gujarat chief minister "to explain whether they are coming close or whether they have made any commitment to each other because she had good relations with the BJP in past".
"She (Banerjee) had worked with them and was in alliance with them. It is for Banerjee or Modi to explain," Ahmed told reporters in Delhi.
"There is no visible basis for praising the Mamata Banerjee government. Can we take it that this political overture will gradually pave the way for Mamata Banerjee to take to the NDA line?" Bhattacharya questioned.
He said Narendra Modi "gave certificates to Mamata Banerjee for her government's performance which is uncalled for at a time when everybody condemns it for non-performance."
The PCC said if the chief minister fails to react to Modi's praise "we will term it as a deep-rooted political equation."
The PCC president claimed that Modi's statement differed sharply with that of the state BJP, "which is opposed to the Mamata Banerjee government's policies and programmes."
Bhattacharya dismissed Modi's charge of discrimination against non-UPA states by the Centre, saying that it was a ploy to cover up a state's failure.
"In the past Jyoti Basu did it and now chief minister Mamata Banerjee is doing the same," he said.
CPI(M) state secretary Biman Bose said it would be unusual if Modi did not pat Banerjee, who sent him flowers on his victory.
