There is no longer any credible argument against fiscal responsibility. Without a sensible approach to public finances and careful use of resources, we cannot hope to achieve economic stability, confidence for businesses to invest, sustainable high-quality public services, and security for future generations.

Eliminating the deficit will be at the forefront of the Chancellor of the Exchequer's mind as he prepares the Comprehensive Spending Review, which will set out the Government's spending plans for the duration of the Parliament. But although it is important that we get public finances under control, this must be done in a way which is fair and measured.

I am strongly opposed to ideological cuts masquerading as economic necessity, particularly those which attack the weak and vulnerable in our society. The Conservatives' proposed cuts to tax credits is an assault on millions of families across the country who rely on this support to help them pay for food, heating, and their children's clothing. The economic recovery cannot rest on the shoulders of the poorest, and those who can afford it must carry their share of the burden. And it is economically stupid to cut the income of people in low paid work. It will reduce the incentive to work.

And the Government should resist the temptation to act in a short-sighted way which will risk the health of the nation and end up costing the country far more in the long run. So we should use this period of historically low interest rates to invest in the country's infrastructure - such as super-fast broadband for all.

I'm also concerned that the Government isn't being straight with people about the scale of the crisis facing the health and social care system. Health leaders know that the Government's target of achieving £20 billion efficiency savings in the NHS over the next five years is virtually impossible, particularly given that demand is rising so fast. And the care system, which so many frail elderly and disabled people rely on, is now at breaking point. Many providers of care are planning on getting out.

It makes plain economic sense to provide extra resources for the NHS and social care. Mental illness alone is estimated to cost the economy around £100 billion each year, while social care plays a crucial role in prevention and relieving the pressure on acute services. If George Osborne has the courage to make a strong commitment in the Spending Review, the economy will reap the long-term benefits of higher employment, improved productivity, and reduced sickness absence and unemployment benefits. The announcement on November 25th will tell us just how serious he is about his 'long term economic plan'.
