Set to take over as Chief Minister of West Bengal on Friday, Trinamool Congress leader Mamata Banerjee today indicated that Congress will join her government in the state.

On her first visit to Delhi after a landslide win in the assembly polls on May 13, the 56-year-old leader met Congress President Sonia Gandhi and Prime Minister Manmohan Singh and invited them to attend the swearing-in ceremony of her ministry in Kolkata on May 20.

Emerging from the meetings, Banerjee said she had invited Congress to be part of the Trinamool-led government in Bengal.

Asked whether whether Congress had agreed, she said, "Congress will be part of the government. I have invited them and they will let me know."

The Railway Minister also dropped enough hints that her portfolio in the Central government would be retained by her party.
