George Osborne has defended his position as Chancellor as MPs prepare to vote to approve his Budget.
Mr Osborne told the Commons that if Britain wanted to build a "strong and compassionate society" the country had to live within its means.
"We have to back business to create jobs and we have to make sure work pays by putting more money into the pockets of working people."
The Chancellor also used his opening remarks to pay tribute to Ian Duncan Smith, who resigned as Work and Pensions Secretary last week over planned controversial cuts to the welfare budget.

Prime Minister David Cameron has tried to calm unrest in his party over the resignation of Iain Duncan Smith, the former worker and pensions secretary.
ITV News political editor Robert Peston reports.
Disability charities have welcomed the government's U-turn over planned cuts to the Personal Independence Payments, known as PIPs.
Michelle Mitchell, chief executive of the MS Society, said:
This will be a huge relief for thousands of people who rely on PIP for vital support to live independently and with dignity.
We hope this marks a watershed moment in Government welfare policy.
Mark Atkinson, chief executive of disability charity Scope, said:
We welcome the government's decision not to go ahead with previously planned changes to PIP.
Life costs more if you are disabled and these extra costs make it extremely hard for disabled people to pay the bills.

Stephen Crabb, the new work and pensions secretary, has announced the government will abandon controversial cuts to the Personal Independence Payments.
"I can tell the House we will not be going ahead with the changes to PIP that had been put forward," he said.
He added that the government would not fill the savings gap left in the budget by the U-turn with further cuts to welfare.
The announcement had been widely anticipated following the resignation of Iain Duncan Smith, Mr Crabb's predecessor.
Mr Crabb paid "huge tribute" to Mr Duncan Smith, and appeared to try to win back the support of disabled people, saying he believed it was possible to do "so much better" for them.
Crabb: "we will not be going ahead" with changes to personal independence payments - & he won't have to fill £1.4bn hole in budget. Amazing
Jeremy Corbyn has lambasted the government's budget, saying it had "fallen apart" within days of its announcement and suggesting the chancellor should resign as a result.
The Labour leader accused David Cameron of "covering up his great friend" George Osborne by allowing the chancellor to avoid answering questions in the House of Commons on a budget that had "inequality at its core".
Mr Corbyn noted that Mr Osborne was not present, while "practically every other cabinet minister is here today" and said the chancellor should "consider his position and look for something else to do".
Mr Cameron responded that the chancellor would be in parliament on Tuesday "winding up the budget debate".
David Cameron has defended the budget and attempted to claw back some of his image as a social reformer amid a row over planned cuts to disability benefits.
The prime minister closed a statement to the House on the EU migrant crisis with a reference to the budget row that was sparked this weekend by the resignation of former work and pensions secretary Iain Duncan Smith.
Mr Cameron said the MP for Chingford and Woodford Green had much to be proud of in helping the government to reform welfare benefits.
He said "we must continue to cut the deficit, control the cost of welfare and live within our means", and highlighted government plans for the introduction of the national living wage and prison reform.
