Aside from the immediate measures taken against those students who headed the protest movement, a series of other organisational repressive measures took place in the political realm. On 13 November, in a session of the Political Bureau, it was decided that the Ministry of Education should draw up "a concrete programme of measures to lead to an improvement in the social composition of students". The first to be targeted were former political detainees who had been allowed to return to the universities in 1955–56. Although the great majority of them had not been involved in the protest movement, Nicolae Ceauşescu explicitly asked for this step to be taken in a speech held in Bucharest on 15 November 1956. Around the same time, Virgil Trofin, secretary of the Central Committee of UTM, declared, "We have to know how many enemies there are in our country and are trying to fight against our party".
