Congress President Sonia Gandhi will take the final decision on the party's participation in the new government in West Bengal after discussing with Trinamool Congress chief Mamata Banerjee.
"The issue will also be discussed at the CWC meeting on Friday and Union finance minister Pranab Mukherjee may make an announcement," WBPCC vice-president Debabrata Basu said here on Friday.
Pranab Mukherjee and AICC general secretary in charge of West Bengal Shakeel Ahmed will arrive here on Saturday, he said.
Basu lauded the leadership of Banerjee for bringing in a change in state politics and hoped that an effective government under her leadership would soon take over for better governance and development in the state.
The Trinamool Congress-Congress victory was 'absolutely upto expectations' and a 'glorious moment' in the state's politics, he said adding he believed that this would bring joy in the people's life.
He congratulated people for their overwhelming support to the alliance candidates to end the 34 year-long Marxist 'misrule' in the state.
The WBPCC vice-president also congratulated Election Commission for its arrangement which, he said, allowed people to exercise their franchise without fear.
