But the former railway minister did not rule out the possibility of reconciling with the Congress party if it decides to scrap foreign direct investment (FDI) in multi-brand retail and the diesel price hike.
"If the Congress rolls back FDI in retail and the fuel price hike, then they can approach us," Roy told a news agency.
He outrightly rejected the possibility of his party joining the National Democratic Alliance (NDA), of which it was a part from 1998 to 2006 except for a brief period in 2001.
The Trinamool quit the Congress-led UPA government over the union government's economic decisions including FDI in retail trade.
What about a Third Front, Roy was asked. "I can't say what will happen in the future," he replied.
But the Trinamool won't be a part of any alliance which includes the Left Front, he added.
The 57-year-old MP said his party will organise nationwide campaigns to explain why it withdrew from the central government. This will kick off in New Delhi's Jantar Mantar Monday.
Kolkata: The Trinamool Congress will never ally with the Bharatiya Janata Party (BJP)-led NDA or join any front that includes the Left, party general secretary Mukul Roy has said.
