Boris Johnson has met Jeremy Corbyn’s attack on the Conservative’s record on education today with incredulity.

Corbyn has gone on the record to complain about class sizes saying that children are packed into classes “like sardines.”

“I really don’t know what all the fuss is about. I used to love it when Nanny let us play sardines. Great fun!” Boris told The Herald.

42,000 children are currently in classes with more than 36 pupils in them. An outrageous number in and of itself let alone the spurious soundbite of 500,000 that is being bandied about in campaign speeches, and on Twitter. For clarity 500,000 are in classes between 31 and 35 pupils, too many, too big.

“This is what happens when your Education Ministers don’t have a proper education. Morgan and Greening went to a comp, Greening didn’t even go to Oxford and Gove got a 2:1. Thickos.” Boris continued.

“How do you expect somebody who didn’t go to Eton and get a double first in Classics from Oxford to sort out something as complicated as class sizes?”

“I suppose they could be home schooled.” He conceded.
