Professional Qualifications Bill [HL]

My Lords, I welcome what my noble friend had to say about returning to this issue on Report. When we do, given that, as the noble Lord, Lord Fox, said, it is our anticipation that future free trade agreements will be implemented in primary legislation, would my noble friend at that time also give us a guarantee that, where there is a choice between using primary legislation to make the necessary legislative changes to implement an international recognition agreement and using a power under this Bill, the Government will use the former to allow this House to scrutinise it in more detail?
