I do not accept that point. Removing this exemption will achieve better value for money in the Government’s support for low-carbon generation by targeting support directly at generators and preventing UK taxpayers from subsidising overseas renewable projects that bring no benefit to the UK. That was the weakness; that was the failure of the existing regime, and it is right that we address it.
I now wish to deal with productivity. As my right hon. friend the Chancellor set out in the recent Budget, the rate of UK productivity has been a historical problem. It is vital to increase our productivity, because that is one of the fastest routes to creating jobs and raising the standard of living for everyone. Earlier this month, we published our productivity plan, setting out how we will tackle this long-term challenge. This Bill implements a number of measures taking this plan forward. A stable tax regime with competitive rates and strong investment incentives is essential to drive productivity forwards. In the previous Parliament, the main rate of corporation tax was cut from 28% to 20% as a central part of the Government’s economic strategy. This Bill goes further, by cutting it to 19% in 2017 and 18% in 2020, saving businesses more than £6 billion by 2021 and giving the UK the lowest rate of corporation tax in the G20.
