The National MP Sam Uffindell says boarding schools in the 90s were a “rough and tumble” environment but the incident which saw him expelled from Kings College was the most serious he was involved in.
Uffindell has admitted he was asked to leave the school when he was 16 after a physical assault on a younger student.
He told Morning Report students would punch and tackle each other.
But his attack on a third former on the last day of term was the only event he mentioned to the National Party selection committee.
He says he regrets the incident.
Uffindell denies that his apology to the victim last year was in preparation for his political career.
