I was amazed that, imho, the only good thing about Gove's last attempt to tit around with GCSEs, about 6 months ago which was having just one exam board so schools couldn't shop around- was thrown out with everything else.
I can't recall but was it a potential legal challenge regarding 'competition', from the various Boards?
But to me, it's so obvious it's not true!
But do convince me otherwise if I'm wrong!
