 Following the realignment of opposition politics in the 1970s, with the fall of the United Party and subsequent rise of the Progressive Federal Party as successor as the official parliamentary opposition, the National Party's authoritarian and apartheid policies faced much stronger parliamentary opposition.In 1979, the PFP launched the "strongest parliamentary measures" possible against the Advocate-General Act, that would prohibit press from reporting on allegations of corruption and irregularities without first having such allegations cleared.PFP Colin Eglin launched the attack on the bill, stating that it was an attempt by the National Party to "muzzle the press and deny the public right to know".
