The new rail regulator Tom Winsor had been Swift's general counsel (1993–95), and adopted a more interventionist and aggressive regulatory approach. At times the relationship was stormy, with Railtrack resisting pressure to improve its performance. In April 2000 it was reported in "The Guardian" that "Railtrack is adopting a deliberate 'culture of defiance' against the rail regulator". Gerald Corbett, Railtrack's chief executive at the time, and Winsor clearly saw things very differently from each other. Railtrack resisted regulatory action to improve its performance, and as the regulator probed ever more deeply, serious shortcomings in the company's stewardship of the network were revealed.
