Irish fashion designer Paul Costelloe has died in London aged 80.

Costelloe became one of the best-known names in British and Irish fashion and was personal designer to the late Diana, the Princess of Wales.

His family issued a statement on Saturday saying they were deeply saddened to announce the passing of Paul Costelloe following a short illness.

They added: He was surrounded by his wife and seven children and passed peacefully in London.

Born in Dublin, Costelloe's father ran a successful raincoat company. After studying design, he moved to Paris and established his own label in 1979, presenting collections at major fashion weeks around the world.

His collaboration with Diana, Princess of Wales, began in 1983 and continued until her untimely death in 1997. Costelloe was known for his use of traditional Irish fabrics, elevating the image of Irish fashion internationally.

Taoiseach Micheál Martin described him as an icon of design who brought Irish fashion to the global stage. Other leaders echoed the sentiment, paying tribute to his extravagant talent and remarkable legacy.
