Oxford University's student union invited Just Stop Oil to host a stall at this year's freshers' fair, the Mail can reveal today.
Daniel Knorr, 21, who stormed Lord's cricket ground during the second Ashes test match this summer, was pictured manning the stand and recruiting students to join the radical eco-protest group.
He also posted 17,000 JSO leaflets to Oxford students via their college cubby holes earlier this week.
It comes despite Education Secretary Gillian Keegan warning last month that students risk ruining their futures if they participate in slow-march protests organised by JSO.
In a letter sent to university vice-chancellors, Mrs Keegan said that institutions must be prepared for 'any heightened risk of unlawful activity taking place' on campuses this year.
Her letter followed a Mail investigation which exposed the group's plot to infiltrate university campuses and build an army of impressionable undergraduates.
Oxford is one of a number of educational institutions where JSO has promoted its cause to students.
Student societies are allowed have a stall at Oxford's freshers' fair for a small fee, subject to approval from the student union.
