Meeting of the Parliament 23 February 2016
No detriment is the principle that we have insisted on all along, and it is the principle that we will continue to insist on.
As I set out, no detriment is not about trying to avoid the responsibility of new powers. Under the no-detriment principle that we set out, we would take responsibility for exercising tax policy and for matching UK economic performance. That is not insignificant. However, we will not take on responsibility over population change, which we do not have the powers to determine.
The principle of no detriment drives everything that we have done, and it will continue to drive the position that we take.
