Obviously the contoversy will surround his semi-eugenics point.
On that he was probably selectively misquoted, but I don't care because the issue is too complicated to be encapsulated in a Daily Mail article.
However I thought the more important and interesting point he was making is that:
1. some students are not academically able
2. it is bad for them to keep them studying academic subjects beyond a certain age
3. it is bad for their more academic peers that they should be kept at school beyond a certain age
4. it is bad for their teachers that they should be kept at school beyond a certain age
5. Therefore the government should drop its fixation with academic education for all, and start providing good vocational education for those that need it.
A win-win-win situation all round.
This is what Switzerland and Germany do.
One can quibble with his take on the details, but it seems an eminently sensible analysis.
My guess is that people will prefer to discuss the controversy
