Security at the headquarters of the Liberal Democrats is to be stepped up after a group of students protesting against rising tuition fees said it would target the building next week.
A nationwide day of walkouts, sit-ins and demonstrations will take place on November 24 as protesters aim to build opposition to the reforms for higher education, which will see annual tuition fees triple in 2012.
More lecturers, including the head of Britain's main higher education union, have signed a petition supporting last week's student protests, which saw windows smashed and fires lit by demonstrators inside the Conservative Party headquarters in central London. More than 50 protesters have been arrested.
Alan Whitaker, the national president of the University and College Union, has added his name to the document, which calls on the public to “rally behind all who were arrested for fighting to defend their education”. The union has officially condemned the violence at the protests.
