Series which finds out what happened to people featured in past BBC documentaries. This edition revisits a 1985 film which followed two opposing Northern Irish politicians - Republican Martin McGuinness, who was alleged to be the IRA's chief of staff, and Unionist Gregory Campbell, who also provoked controversy with his hardline views. Over 20 years later, we find out how much McGuinness and Campbell have changed as they've moved from the edge to the centre of government.
