"We will resign from the ministry. Ministers belonging to the Trinamool Congress will submit resignations to the Prime Minister and at 4:30 PM go to President House to hand over a letter withdrawing our party's support to the government," outgoing Railway Minister Mukul Roy told reporters here.
The Trinamool ministers are scheduled to meet the Prime Minister at 4 PM.
While Roy is a Cabinet Minister, Saugata Ray, Sisir Adhikari, Mohan Jatua, Sultan Ahmed and Sudip Bandopadhyay are ministers of state.
Roy said the Trinamool Congress will launch nationwide protests against FDI in retail.
"Our party has decided to protest against the hike in diesel price, withdrawal of subsidy from LPG and FDI in retail," he said.
Roy dubbed the government decisions as anti-people and said the Trinamool Congress cannot support it.
On Wednesday, Trinamool Congress supremo Mamata Banerjee had announced her decision to withdraw support to the UPA protesting the Centre's decisions to hike diesel prices, withdraw subsidy on cooking gas and allow FDI in multi-brand retail.
