A further movement, the Eelam Revolutionary Organisation of Students (EROS), formed in Manchester and London; it became the backbone of the Eelamist movement in the diaspora, arranging passports and employment for immigrants and levying a heavy tax on them. It became the basis of the Eelamist logistical organization, later taken over entirely by the LTTE. The formation of the Tamil United Liberation Front (TULF) with the Vaddukkodei (Vattukottai) resolution of 1976 led to a hardening of attitudes. The resolution called for the creation of a secular, socialist state of Tamil Eelam, based on the right of self-determination.
