I thank the minister for that and congratulate the Executive on having such a care for Scotland's children. To that end, will he advise his colleagues who are responsible for any of the purchases associated with the new Holyrood project that it is not enough to express a pious hope that materials for that building will not come from China or India and that it is absolutely imperative that strictures must appear in the procurement documents so that we do not have the exploitation of other people's children?
