Do your sums, Rishi

Why does rishi Sunak want every pupil to study maths until the age of 18?

It sounds as easy as pi, but it’s a sine of desperation. It will cause division in the country, multiply the Conservatives’ problems, take away attention from more important matters and add to the average person’s confusion.

This idea is just a fraction of what’s needed to fix the country. rishi mustn’t go off at a tangent. JOHN WHAPSHOTT,
