Church reaction: The Catholic Archbishop of Armagh and Primate of All Ireland, Dr Seán Brady, was among the senior church leaders to extend their sympathies to Mr Haughey's family, following his death yesterday.
Describing him as a "reforming politician" who had considerable success in introducing measures for the disadvantaged in Irish society, Dr Brady said he would also be remembered for pioneering public utility allowance schemes and free transport for the elderly.
"As taoiseach, he played a significant part in initiating good relations with Britain as a key factor in resolving the political problems of Northern Ireland," he added.
The Church of Ireland Archbishop of Dublin, Dr John Neill, also extended his sincere sympathies to Maureen Haughey and her family.
He said Mr Haughey's legacy in Irish life was a "complex and multifaceted" one, which will take time to evaluate. The Haughey family would be in his prayers, he added.
The Catholic Archbishop of Dublin, Dr Diarmuid Martin, also expressed his sympathy to Mr Haughey's family.
The days following his death were "not ones for writing history books", he said. A full and balanced analysis of his impact on Irish life would take "time and careful consideration".
It should be remembered that Mr Haughey was a husband, father, grandfather, brother and friend.
Those closest to him should be afforded these days to grieve with peace and dignity, Dr Martin added.
