Thousands of demonstrators are expected to gather in London on Wednesday in the first high-profile student protest since 2010.
Demo 2012, organised by the National Union of Students, will highlight the lack of employment for young people and tuition fees.
Organisers expect around 10,000 people to assemble near the Embankment in the morning, before a march past Parliament Square towards Kennington Park.
2010 protests saw the "kettling" of crowds by police in freezing conditions. The National Union of Students advised marchers to come with warm clothes and food.
