Dozens of West Point cadets have cheated in one of the biggest exam scandals to hit the elite US military academy in decades, officials say.

More than 70 students were accused of breaking West Point's Cadet Honor Code in a maths test while studying remotely because of the coronavirus pandemic.

Most of the cadets have admitted cheating on May's exam.

Instructors became suspicious when they noticed irregularities while marking the calculus tests.
