It's very difficult to give an answer to that question, because, of course, the private sector is not something that comes under our control, but what we have done, however, of course, is to effectively outlaw zero-hours contracts in the public sector. We want to make sure of this, for example, in the care sector. The care sector is a foundation sector, as far as we are concerned, and we will use our powers to the utmost—we will push the boundaries of our powers—to make sure that zero-hours contracts are not there, as far as the public sector is concerned. There is a job to be done, yet, in terms of ensuring that public sector bodies ensure there are no zero-hours contracts in place when they subcontract, that is an area that still needs some work.
