University students and academics in Oxford have demonstrated against higher education cuts and proposed rises to tuition fees.
About 1,000 students from Oxford and Oxford Brookes universities walked through the city waving placards.
Business Secretary Vince Cable was forced to pull out of a planned seminar on the advice of police.
The protest was organised by the Oxford Education Campaign, made up of students and academics from both universities.
Police attended the protest in Radcliffe Square, which caused some traffic disruption.
Mr Cable had been due to take part in a seminar organised by Brasenose College about life as an MP, but announced on Wednesday it would be postponed.
He told the BBC he was "happy to engage in debate" but labelled the protest "unnecessary" due to the disruption it caused.
The government is preparing to announce its plans for the future funding of England's universities following the Browne Review which called for a lifting of the cap on university tuition fees.
Jonny Medland, from the protest organisers, said they had consulted with the community.
"I think we were very happy with the turnout.
"It's clearly an issue students feel very passionate about."
A Thames Valley Police spokesman said CCTV footage of the demonstration would be monitored to identify those who did not protest peacefully.
