Bandaranaike, but at the same time they distributed posters and pamphlets promising violent rebellion if Bandaranaike did not address the interests of the proletariat.In a manifesto issued during this period, the group used the name Janatha Vimukthi Peramuna for the first time.Because of the subversive tone of these publications, the United National Party government had Wijeweera detained during the elections, but the victorious Bandaranaike ordered his release in July 1970.
