724,000 viewers watched the opening episode of Charlie, RTÉ's new three-part dramatisation of the political career of former Taoiseach Charles J Haughey last night.
An additional 21,000 watched the drama on RTÉ One+1.
Starring former The Wire and Love/Hate actor Aidan Gillen in the lead role and Tom Vaughan-Lawlor as spin doctor PJ Mara, the opening instalment covered Haughey's tooth-and-nail battle for power, his fraught negotiations with British Prime Minister Margaret Thatcher over Northern Ireland, and the fall of his first government in 1981.
In next week's episode, GUBU, Haughey seizes his opportunity to regain power and to lead Ireland onto the stage of world politics - but domestic complications conspire to bring him down.
