Mairead McGuinness MEP and first Vice-President of the European Parliament said she was saddened to learn of the death of Séamus.
“He was Professor of Agricultural Economics in UCD when I was a student.
“I learned a great deal from him,” she said.
“His contribution to analysis of agricultural policy was sharp, incisive and always worth reading and listening to.
“He educated and gave confidence to generations of young ag students, myself included.
“I’d like to extend my deepest sympathies to his family. May he Rest In Peace.”
