Prince William should not be discriminated against because of the circumstances of his birth, a Cambridge University professor has said.
The university has been accused of giving special treatment to the Duke of Cambridge, who got ABC at A-level, but is to start an agricultural course there shortly.
– Prof Ross Anderson, of Cambridge University
Colleagues and I sometimes organise special courses for people from industry who want to learn about the latest research in our field. For this we charge them money.
Every academic has the right to do this, so it is completely unfair of people to criticise poor Borys [Cambridge’s Vice-Chancellor Professor Sir Leszek Borysiewicz].
Whether they have any A-levels at all is no more relevant than the price of tea in China.
Speaking to the Cambridge News, Prof Ross Anderson, of Cambridge University’s Computer Laboratory, defended the rights of his colleagues to produce specialist courses “for people who are prepared to pay for it”.
He added that they should “not be discriminated against on account of the circumstances of their birth”.
Prince William has met with PhD students whom he will be sharing group seminars with on a bespoke course at St John's College, Cambridge University.
The course is part of the executive education programme at the university, and will prepare him for his inheritance of the Duchy of Cornwall estate.
According to a report in the Cambridge News, the modules he is expected to study include farming and supply chains, rural and planning policy, site management, agricultural policy and conservation governance. He will also go on a number of field trips.
The Duke of Cambridge has arrived at St John's College, Cambridge, where he is set to begin a course in agricultural management.
A student newspaper that objected to Prince William's enrolment on a Cambridge University course has withdrawn its criticism.
The Duke of Cambridge is about to start the ten week Agricultural Management course at the School of Technology, to help him prepare for running the Duchy of Cornwall when Prince Charles becomes King.
But student newspaper 'The Tab' questioned whether he had high enough grades to make it onto the course.
Speaking on ITV's Daybreak, the paper's editor Will Heilpern now accepts his enrolment is fair.
"It seemed really unfair that Prince William was coming in to do a degree," he said.
"However, when you actually looks at what he's doing, he's doing a course which is aimed at Boards of Directors and Business Executives so it's not really relevant to compare the grades.
"I was more doing that in a tongue in cheek, jokey manner."
The Duke of Cambridge will return to life as a student today by beginning a course in agricultural management at Cambridge University.
