He was criticised in 1998 when he said that Irish women lacked style.
“Irish women have difficulty with style because it’s not in their inner nature… like the Italians,” he said at the time
However, during an interview with Irish broadcaster RTÉ this year, he said he felt that Ireland was more European than years ago.
