THE BRITISH PRIME Minister has hailed Queen Elizabeth II’s recent visit to Ireland as a “gamechanger” for the two countries.

Speaking in an interview for RTÉ’s documentary The Queen’s Speech, David Cameron said the trip put the relationship between Ireland and Britain into a “massive new perspective”.

Due to be shown at 9.3opm tonight on RTÉ One, the documentary also features Enda Kenny stating a return visit by the President is on the cards.

He believes that after an appropriate amount of time, the president of Ireland will receive an official invitation from Buckingham Palace to make a State visit to Britain.

In turn, Cameron described an Irish Presidential visit to Britain as a “great idea”.

The timing of any such visit is a matter for Buckingham Palace, Cameron added during the interview.

Tonight’s documentary remembers the Queen’s four-day visit and delves behind-the-scenes at the itinerary planning and the writing of that speech.
