I know that is true from talking to the small businesses in my constituency.
The Chancellor claims to want a productivity revolution, but that is given the lie by the fact that in the autumn statement in December and the March Budget he did not announce that the £500,000 allowance would stay or that it would in fact be £200,000. Investment requires long-term confidence—telling businesses well in advance what they can do in terms of investment. The fact that the Chancellor did not tell us, but has produced a rabbit out of a hat in the summer Budget, tells me that he is not that serious.
We have also heard today that the Chancellor intends to cut corporation tax progressively over the spending period to 18%. I do not gainsay that, but I ask the House to look at what happens when cutting corporation tax significantly is combined with a de facto reduction in the annual investment allowance. Surely we want to cut corporation tax to encourage firms to use their surplus capital to invest in plant and machinery. It is therefore necessary to maintain the £500,000 level—or perhaps even raise it further—to encourage firms to put their money into plant and machinery to raise productivity. By de facto cutting the investment allowance from £500,000 to £200,000 at the same time as cutting corporation tax, the Chancellor will encourage firms to keep their surplus capital sitting in the bank, instead of investing in plant and machinery. That is what has been happening in this country, and that is one of the reasons why productivity has fallen since 2008.
