In Continental Europe during the early 1970s , there were instances of the new radicalism turning into Marxist-Leninist paramilitary campaigns ( such as the Red Brigades in Italy and the Baader-Meinhof Group in Germany ) . With the exception of the anarcho-communist Angry Brigade , the far-left in Britain did not widely engage in such activities . However , there were some , mainly ideological , connections to early phases of The Troubles and civil rights movement in Northern Ireland . For instance C. Desmond Greaves ' Connolly Association ( part of the CPGB ) had an ideological influence on the Marxist-Leninist turn of Sinn Féin and the Irish Republican Army ( which , following the split in the republican movement , became the Officials faction ) . Indeed , the perpetrator of the 1972 Aldershot bombing had spent time in the British Maoist CDRCU group . The non-communist Provisionals , who spearheaded the republican campaign , garnered " critical support " from some British Trotskyist groups , most prominently the IMG early on , under the rationale of anti-imperialism and much later in the 1980s had the Trotskyist-orientated People 's Democracy merge into PSF
