Education Bill

I ask my noble friend for a little footnote to history. In checking the affirmative order provided for in Clause 74(4), I see that, whereas we have only an affirmative procedure for statutory instruments affecting these changes, the Welsh have opted for their equivalent for the negative procedure. I wondered what the history to that was. I do not want an answer now but, if there is anything of interest in it, I should like to know what it is.
