The Prince of Wales and the Duchess of Cornwall made their first joint trip to the Republic of Ireland in May 2015. The trip was called an important step in "promoting peace and reconciliation" by the British Embassy. During the trip, Charles shook hands with Sinn Féin and supposed IRA leader Gerry Adams in Galway, which was described by the media as a "historic handshake" and a "significant moment for Anglo-Irish relations". In the run up to the Prince's visit, two Irish republican dissidents were arrested for planning a bomb attack. Semtex and rockets were found at the Dublin home of suspect Donal O'Coisdealbha, member of a self-styled "Óglaigh na hÉireann" organisation, who was later jailed for five and a half years. He was connected to a veteran republican, Seamus McGrane of County Louth, a member of the Real IRA, who was jailed for 11 and a half years. In 2015, it was revealed that Prince Charles had access to confidential UK cabinet papers.
