The British-Irish relationship has been typified by close cooperation since the 1980s, culminating in the 1998 Good Friday Agreement. However, Brexit has created challenges and at times the rhetoric between the British and Irish governments has been heated. It was in response to the perceived need to avoid megaphone diplomacy in the 1980s, following the 1982 Falklands War and the 1981 H-Block hunger strikes where 13 hunger strikers died, that the British-Irish relationship was institutionalised in the 1985 Anglo-Irish Agreement. Arguably, Brexit’s challenges justify a commitment to using existing British-Irish institutions more fully or to creating new ones.
