In 1968, the IS put out an appeal for revolutionary unity, aiming the appeal at the industrial militants aligned with the Communist Party, although it was also directed at the newly formed International Marxist Group (IMG) and the libertarian Solidarity group. In the event only the small Workers' Fight group responded favourably and as soon as they became members of the IS they constituted themselves as the Trotskyist Tendency (TT) faction. The TT was expelled from IS after it attempted to galvanise opposition to the group's leadership on political issues including Ireland and the European Union and on the question of internal democracy. At the conference at which what the leadership called "defusion" took place, 40% of the delegates voted against. Now substantially larger than when it had entered IS, the TT reconstituted itself as Workers' Fight, and still exists today in the form of the Alliance for Workers' Liberty.
