Dunne increases shares to 24.03%
His intention is to build to a level of 29.9% of the equity to place him on an equal footing with the Doyle family.
Mr Dunne previously clinched a deal with the Jurys Doyle board for the purchase of 4.8 acres of its prestige Ballsbridge site for €260 million. It is understood the Doyle family will vote on 27 September to sell to Mr Dunne.
