The Central Bank has expressed its growing exasperation with Irish banks, and has hinted at imposing individual fines and claw backing pay of top Irish bank chiefs if they fail to come into line following their handling of the €1bn tracker mortgage overcharging scandal.

Former Permanent TSB chief executive David Guinane has claimed before the High Court he is entitled to a severance payment of over €866,000 following his departure from the bank in 2012.
