His work included profiles of former SDLP leader John Hume and ex-Ulster Unionist Party leader David Trimble, both of whom played significant roles in advancing peace in the North. Walker's career spanned decades, during which he provided in-depth coverage of complex political developments. His death has prompted a reflection on his impact on journalism and his lasting influence on the understanding of Northern Ireland's political landscape.
