However, for much of the 1960s the most important group publication was "Young Guard". Working within the Young Socialists the IS had issued a youth magazine called "Rebel" from 1960 onwards as the YS was, along with similarly youth oriented Campaign for Nuclear Disarmament, the greatest source of recruits to IS. Within the highly factionalised atmosphere of the YS, however, "Rebel" soon disappeared as the IS forged an alliance with the supporters of Ted Grant around the "Rally" paper. The two tendencies jointly launched "Young Guard" as their challenge to both Transport House and the Keep Left grouping of Gerry Healy's supporters. The editorial content and most contributors to "Young Guard" were firmly in support of IS, with Grant's supporters playing a minor role. After Healy's followers in the Socialist Labour League left what was renamed the Labour Party Young Socialists, IS was briefly able to take the leadership of that organisation. But by this point much of the life had gone out of the youth movement and "Young Guard" ceased publication in 1965, being superseded by a new run of "Rebel" which lasted in its turn until 1967. By this time though, IS as a whole was drifting away from entrist work within the Labour Party as the industrial struggle developed.
