The historic May visit of Queen Elizabeth to Ireland has been described by UK Prime Minister David Cameron, as a "game-changer" that heralded a new era in Anglo-Irish relations.
In the RTE documentary, “The Queen's Speech” broadcast last night, Cameron said the “strong relationship” between London and Dublin has been further bolstered as a result of the visit.
In May, Queen Elizabeth became the first monarch to visit the Republic in over a century. Her four day visit sparked an unprecedented multi-million security operation.

The British Prime Minister told RTE, "It's been a game-changer, to use that terrible modern expression.
"What was already a strong relationship, and what was already becoming warmer and more positive because of the settling down of the Northern Irish issue, I think her visit has just put that into a massive new perspective.
"She just warmed the hearts of people, and so this true relationship - that I think had been going on between British people and Irish people for years - has really now been able to flower."
