RISHI SUNAK admitted today that England lacks enough teachers to deliver the subject to all under-16s, leaving his proposed “maths to 18” policy in serious doubt.

The Prime Minister’s admission came after he reiterated his pledge to ensure all pupils in England study some form of the subject until the age of 18.

The National Education Union stressed the government has repeatedly missed its recruitment targets for the austerity-hit sector, while school leaders’ union ASCL slammed the “vague and poorly thought-out policy” as a distraction from ongoing national education strikes.
