Technology giants Apple Inc are to be formally investigated over its tax arrangements in Ireland, the European Commission has said.
Last year it was revealed the company had cut billions from its tax by declaring companies in Cork and not tax resident in any other country.
The EU's competition authority has been looking into corporate tax arrangements in several member states.
Almost 800 babies were buried in a concrete, septic tank in the grounds of a home for unmarried mothers in Galway between 1925 and 1961, according to research by a historian.
The bodies of 798 children were buried at the Tuam mother and baby home, which was run by The Sisters of Bon Secours.
In 1975 the grave was found by two local boys, but the scale of bodies was not examined until recently, after historian Catherine Corless made repeated requests to the state for official records.
The site is believed to be one of 10 similar homes across Ireland - three others are believed to hold the remains of another 3,200 babies and infants.
The scandal has sparked renewed calls for the Irish Government to hold a public investigation.
Moody's upgraded Ireland to investment grade in January, handing the government a major boost a month after it completed the European Union/International Monetary Fund bailout.
Moody's upgrade means that all of the three main rating agencies now have Ireland rated at BBB+, or equivalent, which clearly ranks Ireland as an investment-grade credit and reflects the confidence in Ireland shared by investors generally.
With Irish debt already rallying, that upgrade further opened it up to investors prohibited from buying junk-rated paper. Ireland's bailout exit has been relatively smooth, having made a strong return to bond markets and with an economy set to grow about two per cent this year.
At the height of the euro zone crisis in July 2011, Moody's cut Ireland's rating to Ba1, one notch below former financial market pariah Colombia, and that prohibited large, mainly Asian-based ratings-sensitive funds from touching Irish debt.
Credit agency Moody's Investors Service upgraded Ireland's credit rating adding a further vote of confidence to the first euro zone country to complete an EU/IMF bailout last year.
"Ireland's credit profile is recovering more quickly from the euro area debt crisis as a result of its economy's dynamism and growth prospects," the credit agency said in a statement.
"However, Ireland's credit profile and rating remain constrained by the country's high public debt level, still-sizeable fiscal deficits and significant banking sector risks, including a high stock of non-performing loans."
Moody's raised Ireland's rating by two notches to Baa1 from Baa3 and with a stable outlook, saying a recent pick-up in growth momentum would speed up fiscal consolidation and cut government debt faster.
Irish president Michael D Higgins has hailed his "memorable" historic state visit to the UK as "so positive, so uplifting and so hopeful".
He took to the Royal Albert Hall stage at a concert in his honour to uproarious applause and said: "On a night like this it is great to be Irish." He added it was "even better" to share it with "our friends in Britain".
On the final night of his visit, President Higgins was joined in the Royal Box by his wife Sabina and Prince and Princess Michael of Kent.
"In this magnificent venue and on this...historical occasion, I want to extend my thanks to a number of people who have made this evening's celebration, and indeed the past few days, extraordinary and memorable days, so positive, so uplifting and so hopeful," President Higgins said.

Irish President Michael D Higgins met Prime Minister David Cameron in Downing Street today as he began day two of his state visit to Britain.
Lord Tebbit has come under fire after suggesting he hoped Sinn Fein politician Martin McGuinness would be "shot in the back".
The former Conservative chairman, who was himself injured in the 1984 Brighton hotel bombing, suggested Mr McGuinness' presence yesterday at a state banquet with the Queen might anger hardline Republicans.
"There's always the possibility that a member of the Real IRA will be so outraged by Mr McGuinness bowing to the Queen that they might shoot him in the back for it. We can but hope," he said.
Sinn Fein leader Gerry Adams expressed outrage at the comments, saying:
"To publicly advocate the assassination of Deputy First Minister Martin McGuinness is a shocking throwback to a violent past from which we are seeking to move on."
Irish president Michael D Higgins will meet Prime Minister David Cameron in Downing Street on day two of his state visit to Britain.
Mr Higgins will also attend an event to mark the contribution of the Irish people to the NHS and meet with the Mayor of London Boris Johnson.
A private but significant engagement will take place at the start of the day when the Duke of York shows the president the colours of the six disbanded Irish regiments which have been preserved in Windsor since 1922.
Mr Higgins will inspect a piece of history in safekeeping for 92 years at the behest of King George V after 200,000 Irish men enlisted to fight for the Crown.
Michael Higgins is the first Irish President to make a state visit to the UK, ending the day with a state banquet at Windsor Castle.Read the full story ›
