Pick of the Day

Partition, 1921, 9.35pm, RTÉ One

Streaming on RTÉ Player

Former UK minister Michael Portillo presents this brand new documentary series.

The Irish Question, which had plagued the British establishment from the early 19th century, essentially became the Ulster Question in the 1910s.

Here, Portillo unravels a web of mystery and intrigue woven by the British ruling classes for whom the essential issue was defending Ulster.

He examines how Ireland came to be divided, how Irish demands for self-government could be reconciled with Ulster unionists' desire to remain British, with the answer being the creation of a Unionist-dominated six-county state, with the remaining 26 forming an independent Ireland.
