Taoiseach Micheál Martin became visibly emotional while visiting a Singapore prison where his uncle was held captive for three years by the Japanese Army during World War II.
Philip Finbarr Martin was freed from Changi prison in 1945 and Mr Martin toured the site on Friday which has been recreated as a museum and chapel.
Philip Martin was imprisoned for three years after the fall of Singapore to the Japanese in 1942 while serving with the British Royal Engineers.
