Railway Minister and Trinamool Congress all-India general secretary Mukul Roy told PTI that though a "personal invitation" has been extended to her to attend the dinner, Banerjee, also West Bengal Chief Minister, would not be able to make it because of her "pre-occupation" in the state.
Roy, a close aide of Banerjee, said he is likely to attend the dinner with some other party MPs.
"It is basically a dinner extended by the Prime Minister every year to all MPs of the UPA and Banerjee is not an MP now," he added.
