A wave of fresh protests against increases in university tuition fees will be held on Wednesday, with a series of occupations, rallies and marches by student activists.
Organisers said feelings were still running high following the demonstration by 50,000 students and lecturers two weeks ago which ended in violence.
A group of activists smashed windows, threw missiles and lit fires at 30 Millbank, the building housing Tory Party headquarters, leading to more than 60 arrests and dozens injured and taken to hospital.
Police, supported by the National Public Order Intelligence Unit, have been monitoring all sources of information in a bid to anticipate the protests.
Senior officers do not want to be caught out again by the unexpected splintering of the march on November 10, organised by the National Union of Students and the University and College Union, that preceded the Millbank riot.
Walk-outs, protests and marches have been organised in towns and cities across the UK, with school and college students expected to join the action.
University workers are organising joint rallies with students in cities including Birmingham, Glasgow, Manchester and Cambridge.
A rally will be held in London’s Trafalgar Square followed by a march to Parliament and a protest outside the headquarters of the Liberal Democrat headquarters and later in Downing Street.
The Sheffield offices of the Deputy Prime Minister and leader of the Liberal Democrats, Nick Clegg are also expected to be targeted for action.
The Lib Dems have come under intense fire over Government plans to charge students as much as £9,000 per year in fees from 2012 after pledging before the general election to oppose any hike.
