Pick of the day

Whistleblower: the Maurice McCabe Story, 9.35pm, RTÉ One

For the first time, and exclusively for RTÉ, Maurice and Lorraine McCabe will tell their personal story in this two-part documentary.

Using candid interviews and extraordinary archive, here's the story of an intensely-private family catapulted into a media spotlight after Sergeant McCabe became the country’s most prominent Garda whistle-blower.

Katie Hannon details the events that saw Sergeant become isolated and ostracised within the force for simply doing what he saw as the right thing. He also became the victim of a whispering campaign that led to the establishment a Tribunal of Inquiry, chaired by Mr Justice Peter Charleton.

The story of Maurice McCabe has rarely been out of the headlines. It has shaken the establishment and rippled through the highest echelons of Irish society from An Gárda Síochána through the media and government.

The second part is broadcast tomorrow (Tuesday) night at 9:35pm.
