In case you were in doubt, Michael Gove has made it crystal clear he does not agree with the Welsh education minister.
But in front of the Education Select Committee this morning, the Education Secretary condemned what Mr Andrews did. He called it 'irresponsible', 'mistaken' and a 'regrettable political intervention' and told him to think again.
He even went as far as to say that it's children in Wales who've been disadvantaged because of this decision to upgrade marks.
I doubt many students in England will agree. So expect more legal challenges from schools and individuals in England.
