Trinamool Congress chief Mamata Banerjee will call on Governor M.K. Narayanan at Raj Bhavan this evening to formally stake claim to form government in West Bengal.

Raj Bhavan sources said that Ms. Banerjee would meet the Governor at 6.30 pm.

Armed with a massive majority and inflicting a crushing defeat on the ruling Left Front, Trinamool Congress is all set to form the next government in the state.

Earlier, Mr. Buddhadeb Bhattacharjee stepped down as chief minister and submitted resignation of his council of ministers to the Governor.

The Governor requested Mr. Bhattacharjee to continue till alternative arrangements were made.
