Blake's speaking out of his proverbial ass:
"All degrees are of equal worth and to ignore this is to ignore the quality assessments and external examinations in place"
While there are some semblance of external assessment in university exams, anyone who's seen Oxbridge finals papers and compared them to a university that asks for EE grades, will find a stark difference. True, there's probably little difference between Oxbridge and many top universities exams, but there's no way the exams of some universities much lower down the tables are as hard as those of top universities.
Oxbridge selects pretty much only straight A people, and yet only 15% or so get 1sts. To say that people who get EE or a levels close to that could pass an Oxbridge exam and get a first seems silly to me.
I can't wait until someone does a test by getting some people at uni to take exams from different universities and see the difference in grades. A 1st from Oxbridge may be worth something similar to a first from London, Warwick, York, Nottingham et. al., but all firsts are not the same, and all degrees are not the same.
