In an interview with Mary Holland on London Weekend Television's "Weekend World" on 17 November 1974, Ó Conaill claimed there would be an escalation of IRA violence. Four days later on 21 November the IRA detonated bombs in two pubs in Birmingham, killing 21 civilians. This was not what Ó Conaill had intended, as the Provisional IRA leadership did not endorse indiscriminate bombing in England. The interview and the attacks led to the introduction of the Prevention of Terrorism Act in the United Kingdom. The interview prompted hostile questions in the Parliament of the United Kingdom.
