On the last point, given that the ongoing cost is not known yet, there remain some issues to resolve.
There is a challenge, not for politicians, but for the businesses that have campaigned for the devolution of corporation tax. As the shadow Secretary of State said, those businesses have a responsibility not to use their profits simply to pay higher salaries for managers, for shareholders or for vanity projects. Having campaigned for this change, and given its implications for expenditure in Northern Ireland, they have a responsibility to ensure that the additional money that results from forgoing tax revenue is invested in their companies to increase productivity, make them more competitive and create better-paid jobs. Only then will this campaign have been a success.
