In 1968 I was a student at Guildford School of Art. The students were unhappy at the quality of the courses and asked to discuss possible improvements with the governors. They refused and the sit-in began. It became the longest ever sit-in at an educational establishment in the UK and led directly to schools, colleges and universities inviting students and staff on to their Advisory Boards. These are photos of the events taken from the inside, start to finish.
