Maureen Haughey - the wife of former Taoiseach Charles Haughey - has died this morning aged 91.
Her son, Fianna Fail TD Sean Haughey, tweeted to say his wonderful mother had passed away peacefully:

Fianna Fail leader Micheál Martin has also extended his deepest sympathies.
Mr Martin says he and the entire Fianna Fáil organisation across the country send their condolences to the Haughey and Lemass families on the passing of a 'wonderfully warm, dignified and intelligent woman'.
Maureen was part of a political dynasty - being the daughter of another former Taoiseach Seán Lemass.
She is survived by her children Eimear, Conor, Ciaran, and Seán.
