Politicians at Dublins Web Summit downplayed the impact of scrapping the controversial measure, despite criticism from a former Apple boss suggesting the country would lose its competitive edge. After the Ireland moved last month to close a lucrative tax loophole, former Apple chief executive John Sculley told the summit that the country risked losing the edge that has helped it become the European headquarters of US technology giants including Apple and Facebook. There is a lot of talent in Ireland so I dont think it will be an insurmountable problem but it will take the edge off, if tax advantages do go away, he said.
