The Muldoon administration, which favoured interventionist economic policies, arouses mixed opinions amongst the free-market adherents of the modern National. Bill Birch's "Think Big" initiatives, designed to invest public money in energy self-sufficiency, stand in contrast to the party's views. Muldoon's autocratic leadership style became increasingly unpopular with both the public and the party, and together with disgruntlement over economic policy led to an attempted leadership change in 1980. Led by ministers Derek Quigley, Jim McLay, and Jim Bolger, the challenge (dubbed the "colonels' coup") against Muldoon aimed to replace him with Brian Talboys, his deputy. However, the plan collapsed as the result of Talboys' unwillingness, and Muldoon kept his position.
