History rewritten as to why Charles Haughey left office in 'Charlie'

The final episode of the series which aired last night will add fuel to the debate as to why Haughey, who had survived repeated threats to his leadership, finally caved in over claims by his former justice minister Sean Doherty that Haughey had known he tapped journalists’ phones in 1982.
It is public record that Fianna Fáil’s hostile coalition partners, the Progressive Democrats, told Haughey they would pull the plug on the government if he did not step down following the revelations in early 1992.
