 Increasingly positive relations between the two states required the two states to explore imaginative work-arounds to the disagreement.For example, while the United Kingdom would not agree to refer to Mary Robinson as "President of Ireland" on an official visit to Queen Elizabeth II (the first such visit in the two states' history), they agreed to refer to her instead as "President Robinson of Ireland".As a consequence of the Northern Ireland peace process, Articles 2 and 3 were changed in 1999 formalising shared Irish and British citizenship in Northern Ireland, removing the irredentist claim and making provisions for common "[institutions] with executive powers and functions ... in respect of all or any part of the island."
