Ireland Steels Itself For A Visit From The Queen

Queen Elizabeth pays a state visit to the Republic of Ireland this week. The four-day trip is the first by a British Monarch in 100 years. Relations between the two nations have been tense since the Republic's 1921 independence and partition from the north and the decades of intermittent violence. Liane Hansen speaks with Irish journalist Conor O'Clery about the Queen's visit.
