Ms Nóirín O?Sullivan:

If I could just clarify, when I am talking about the internal interpersonal differences, it actually relates to the letter of 24 October. We absolutely recognise the need to have the internal governance structures in place. Back in 2015, Mr. Barrett did the right thing bringing this into place. He was there but there was also a new management team there. That should not be lost sight of. We were absolutely committed to making sure a light was shone on these matters. In our modernisation and renewal programme, one of the first things we committed to doing was strengthening governance arrangements within the organisation, including those internal structures - the mechanisms and checks and balances - and ensuring we were complying with best corporate governance standards for the public sector.
