The owner of the Castle Leslie Estate, Sir John 'Jack' Leslie has passed away at the age of 99. 

Leslie was a World War II veteran who was captured at Dunkirk while serving as an officer in the Irish Guards and spent five years as a prisoner of war. After his release at the end of the war he spent years travelling the world before settling in the family home, Castle Leslie, Monaghan in his 70s. 

Sir John became a keen clubber, developing a huge interest in house music. He was a regular in Monaghan's nightclubs and celebrated his 84th birthday in Ibiza. 

Last November, he was awarded the Legion d'Honneur in the French Ambassador's residence on Ailesbury Road. He said he was accepting France's top military award "on behalf of all soldiers from the island of Ireland who fought and died between the two great wars".
