The TV star expresses his heartbreak as his brother, a beloved Catholic priest, passes away following a brief illness.

Declan Donnelly has expressed his profound sorrow after the death of his brother, Father Dermott Donnelly, who passed away at the age of 55. The Catholic priest died peacefully in hospital on Friday afternoon after a short illness, as confirmed by the Diocese of Hexham and Newcastle.

In a heartfelt post on Twitter, Declan, 46, shared the news with his followers, writing: “I am heartbroken to tell you that my darling brother Fr Dermott, @TweeterPriest, sadly passed away this afternoon. We are all beyond devastated. Thank you for your messages of sympathy and support, they are appreciated DD.”

Father Dermott, a cherished figure within his community, had served for over 30 years, primarily at St Joseph’s Church in Stanley, County Durham. His death has left many shocked, with the Diocese describing it as a “great loss.” A statement from the Diocese asked for prayers for his soul and for his family, especially his mother, during this difficult time.

Bishop Robert Byrne of Hexham and Newcastle praised Father Dermott for his exceptional dedication, particularly in his work with young people and youth ministry. “He will be sorely missed for his energy, enthusiasm, and ability to engage with all who met him,” said the Bishop, adding that Father Dermott had played a pivotal role in bringing disadvantaged youth closer to faith.

The priest had recently celebrated 30 years of service and was known for his vibrant personality and deep commitment to his parishioners. His work with young people, many of whom came from difficult backgrounds, was especially noteworthy. He was instrumental in organizing and leading events such as the Flame gatherings at Wembley Arena, which brought together thousands of young Catholics.

Father Dermott was also a strong supporter of various charities, including The Catholic Agency for Overseas Development (Cafod), where his passion for social justice and service to the most vulnerable was widely acknowledged. Monica Conmee, head of education at Cafod, paid tribute, recalling Father Dermott’s “immense talent and gifts” in guiding young people to experience God’s love.

Before his death, Father Dermott had been reported as being critically ill, with local parishes, including Stanley, Dipton & Byermoor Catholic Parishes, requesting prayers for him. His passing has been met with an outpouring of tributes from those who knew him, with many reflecting on his kindness, warmth, and unwavering faith.

In 2014, Father Dermott appeared on Songs of Praise, alongside CBBC’s Hacker T Dog, to answer questions about the Church posed by young viewers. His legacy will live on, not only in his community but through the countless lives he touched throughout his career.

A prayer gathering will be held at St Joseph’s Church in Stanley at 6 pm on July 8 to honour Father Dermott and celebrate his life and work. The Donnelly family, including Declan, continues to receive messages of sympathy as they mourn their loss.
