A wave of fresh protests against increases in university tuition fees are set to be held on Wednesday, with a series of occupations, rallies and marches by student activists due to take place in cities including Birmingham.
Organisers said feelings were still running high following the demonstration by 50,000 students and lecturers two weeks ago, which ended in a group of activists smashing windows, throwing missiles and lighting fires at 30 Millbank, the building housing Conservative Party headquarters.
Police, supported by the National Public Order Intelligence Unit (NPOIU), have been monitoring all sources of information in a bid to anticipate Wednesday's 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 (NUS) and the University and College Union (UCU), that preceded the Millbank riot.
Walk-outs, protests and marches have been organised for Wednesday in towns and cities across England and Wales, 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.
The protest has been dubbed Day X, with parents and teachers, trade unionists, pensioners, disability and housing activists invited to join students for the protest at Downing Street.
Many of the protests have been organised by the Education Activist Network and the campaign group Youth Fight For Jobs, whose spokesman Paul Callanan said increases in tuition fees coupled with spending cuts will lead to a two tier education system.
"Education will become a privilege for the few that can afford it. The 50,000 strong protest on the 10th was a huge demonstration of anger from students who want to fight for the right to a decent future."
Commander Bob Broadhurst, who will oversee the response of police in London, said it was "far too early" to give an estimate of numbers.
He said: "We would like to reassure people that we are doing all we can to make sure those who want to peacefully protest are able to do so, but we will not tolerate criminal activity, violence and disorder."
The Met has appealed to all protest groups to speak to officers about their plans, whatever form of protest they intend to take.
