Ottawa  - Prime Minister Stephen Harper Wednesday appealed to Canadians to support his minority government and vowed to fight a no-confidence vote in parliament by the opposition.

In a nationally-televised address Harper accused the opposition on Wednesday evening of wanting to overturn the results of the latest general elections only seven weeks after the poll.

Canada's government would fight its opponents by all means at its disposal to prevent them from forming a coalition government to replace his own, Harper said.

"Tonight, I pledge to you that Canada's government will use every legal means at our disposal to protect our democracy, protect our economy and to protect Canada," he said.

The opposition leftist NDP, the Liberals and the separatist Bloc Quebecois on Monday announced plans to form a power-sharing coalition to replace Harper's minority government as early as next week.

The opposition accuses Harper of failing to propose measures to stimulate the Canadian economy.

Harper warned against any government including the separatists. "Canada's government cannot enter into a power-sharing coalition with a separatist party at a time of global insecurity," he said. "Canada's government must stand unequivocally for keeping the country together."

Harper's conservatives strengthened their position in the October 14 snap election, but failed to gain an absolute majority. (dpa)
