Students crowd the main entrance of the London School of Economics today - 14 March - as they continued their sit down strike which began last night . They are protesting against the suspension of two students , Mr David Adelstein , president of the Students Union and Mr Marshall Bloom , president of the Graduates' Association . More than four hundred students took part in the protest . Adelstein and Bloom were suspended by the school board until the end of the summer term for disobeying an order not to hold a students' meeting . 14 March 1967
