"Your remarkable victory for a second consecutive term is indeed an achievement to be celebrated," she told Banerjee.
In a letter to the TMC supremo, Jayalalithaa also thanked Banerjee for inviting her for the May 27 swearing-in ceremony as Chief Minister of West Bengal but said she cannot attend it though she "would have liked to."
"Though I would have liked to attend the ceremony and wish you all the best in person, I am unable to do so, due to pressing official commitments," she said.
