What steps she is taking to help ensure sustainable public finances.

In July, a Treasury assessment of public spending showed that this Government inherited a £22 billion black hole in the public finances. I took immediate action—[Interruption.] Those on the Opposition Benches may not like it, but it is true. [Interruption.]

Order. I cannot hear the Chancellor, and I will hear the Chancellor.

There are not many Conservative Members, but they still make quite a lot of noise.

I took immediate action by identifying savings and making reforms to the spending and fiscal framework to ensure that never again can a Government be allowed to make unfunded commitments, and to leave their successors with a massive black hole, as the Leader of the Opposition and the previous Chancellor did. As my right hon. Friend the Chief Secretary to the Treasury said to the House yesterday, the Budget will confirm the detail of the robust fiscal rules—this was set out in our manifesto—and will set out tax and spending plans, alongside an updated forecast from the independent Office for Budget Responsibility.

Does my right hon. Friend agree that being honest and transparent about the state of public finances is the right thing to do, and that having a long-term plan to fix the foundations of our economy and the public finances is preferable to the short-term, chaotic approach taken by the SNP in Scotland, which has led to three consecutive years of emergency in-year budget cuts?

This Government are committed to sustainable public finances, unlike two of the Opposition parties. A stable economy built on stable public finances is a key foundation for growth, which is why Labour is on the Government Benches, and the SNP and the Tories are on the Opposition Benches. The robust fiscal rules set out in our manifesto will put the public finances on a sustainable path, so that we can move the budget into balance, with day-to-day costs being met by revenues, and get debt falling as a share of our economy. Given our challenging inheritance, that will require difficult choices, but this Government will make them to fix the foundations of our economy.

The last Government left Eastbourne borough council in a position in which it spends 49p in every pound it collects in council tax on temporary accommodation. We need a solution, because that is not sustainable for councils or families. Will the Chancellor commit to supporting councils with the cost of temporary accommodation, and to investing in preventing homelessness in the first place?

The hon. Member is absolutely right: the number of people housed in temporary accommodation is a scandal, and the amount that costs taxpayers in Eastbourne and around the country is a double scandal. We made a commitment in our manifesto to building 1.5 million homes during this Parliament. Conservative Members oppose that, but we are determined to do it, because that is the way to bring down the cost of temporary accommodation and ensure that all families have a safe and secure roof over their heads.

My right hon. Friend is right about the challenge it will be for the Government to balance the public finances. A stiff target of 2% in-year efficiency savings has been set for Departments. What is she doing to make sure that the target is robustly applied, and that Departments do not game it by putting off decisions, which will end up costing more?

I thank the Chair of the Treasury Committee for that question. She is absolutely right that in our July statement, we set a 2% productivity target, not just for the Department of Health and Social Care, as the previous Government did, but for all Departments. Ministers are absolutely determined to deliver against those targets, because that is the way to ensure that we have resources for the frontline public services—our schools, hospitals and police—that we all rely on.

Under the last Government, the Chancellor said that interest rates and gilt yields were driven by Government policy. Will the Chancellor guarantee that neither will rise higher than they did under the Conservatives?

The last Government crashed the economy with a mini-Budget and sent interest rates and mortgage rates soaring, putting huge pressure on the costs borne by families and businesses. We will set out our Budget tomorrow, including robust fiscal rules on paying for day-to-day spending through tax receipts and borrowing only to invest, whereas the previous Government borrowed for day-to-day spending, which is why we are in the mess we are in today.

I call the shadow Minister.

Last Wednesday, in Washington, the Chancellor announced changes to the debt rules to allow Labour to borrow more. However, published Treasury advice says that increasing borrowing risks interest rates staying higher for longer. Does the Chancellor agree with her Treasury civil servants?

Last week, when I was in Washington, I was very pleased to hear the International Monetary Fund say how important it is that countries, including the UK, borrow to invest in their capital infrastructure. Under the plans we inherited from the previous Government, capital spending as a share of GDP is due to fall from 2.6% to 1.7%. If those decisions were to go forward, it would mean plans delayed and cancelled. We will set out our plans tomorrow in the Budget, but it is crucial that we have rules ensuring that we pay for day-to-day spending through tax receipts, and that we borrow only to invest, unlike the previous Government.
