Constitutional Reform and Governance Bill

I want to ask about the necessity of this clause. The Father of the House might correct me, but I do not remember its being referred to in the Public Accounts Commission's report. Whenever one sees a clause that creates powers to do something that has been done for a very long time, it sets alarm bells ringing. May I ask the Minister whether there is any doubt that the CAG has the power to enter into the type of agreement referred to in the clause, or any doubt about whether anything done in the past is valid?
