North Antrim MP Ian Paisley said,
"It is with great sadness that I learnt this morning of the passing of world renowned professor Jim Dornan. I wish to express to his wife Samina and his children Jamie, Liesa, and Jessica my profound sadness.
Jim was a wonderful man, he was engaged in political lobbying and promotion of many medical and non medical issues. Above all he loved Northern Ireland and was so proud of this place. His ambition, expressed often to me, was to see Northern Ireland and its people flourish and be the best. No obstacle was ever insurmountable for him and he was a great source of encouragement.
I will miss our many chats and text messages and his ability to challenge and encourage change."
