“I am so sad to hear of the passing of Sr Stanislaus Kennedy – known fondly and widely as Sr Stan – who has died at the age of 86. She was an incredible activist and advocate.

“I last met her in May, as the charity she founded – Focus Ireland – were turning the sod of new social and affordable homes in Cabra, a typical example of the valuable difference she and her charity continued make to help the most disadvantaged.

“Sr Stan sought, throughout her entire life, to ensure the voices of those most marginalised or forgotten, including those who are homeless or new to this country, were raised. She charged the state to do better and deliver more, and she was right.

“My thoughts and prayers are with Sr Stan's family and loved ones at this time. Ar dheis Dé go raibh a hanam.”
