I am grateful to Prime Minister, Sonia, says Mamata
"The Prime Minister sent me a congratulatory message from Afghanistan for our victory. I am overwhelmed. I am grateful to him," she said while addressing the media and party men outside her Kalighat office.
Banerjee said she was also grateful to Congress president Sonia Gandhi who also sent similar message to her.
Many other political leaders have sent such messages, she said.
