'Expected' is educationspeak. Every parent has come across it at parents' evening or whatever. . So it gets stuck in manifestoes - not just Tory ones - because it sounds educationish.
But the subject matter, a politics of nostalgia meme, sucks the educationishness of it away. It isn't in a list, it is stuck in the middle of a discursive paragraph but pops out like an unruly pubic hair. Knowing one's time tables by heart has nothing to do with numeracy but is a dog whistle to the good old days when these things happened.
