LONDON: Finance minister warned on Saturday that Britain faces its toughest spending cuts in two decades if the ruling wins this year's general election.
Darling also confirmed to The Times newspaper that there would be a budget before the election, which must take place by June.
That will quash speculation that Prime Minister Gordon Brown is preparing to call an early election.
Darling, the, said in an interview that severe spending restraints were "non-negotiable" if he is to bring down the 178 billion pound (198 billion euro, 285 billion dollar) budget deficit.
"My priority is to get borrowing down. Once recovery is established, we have to act," he said.
"The next spending review will be the toughest we have had for 20 years... to me, cutting the borrowing was never negotiable. Gordon accepts that, he knows that."
Darling told the newspaper that voters supported his effort to balance the books.
"Most people know that public spending has doubled over the last 10 to 12 years, so we are coming off a much higher base," he said.
"We are not talking about a situation where we have already cut to the bone."
Darling was speaking after two former ministers, Geoff Hoon and Patricia Hewitt, launched a failed attempt to unseat Brown.
Opinion polls suggest the opposition Conservatives will win the general election.
