Britain's fiscal watchdog today increased its estimate of the likely loss to taxpayers from the 2008 rescue of Royal Bank of Scotland to £31 billion, up £2.4 billion from October. 

The increase came mainly from four more months of servicing debt on the bailout, Britain's Office for Budget Responsibility said on the same day finance minister Philip Hammond set out his latest budget plans. 

The widening loss to the UK government from the bailout came despite RBS paying a special dividend on its annual profits in 2018 for the first time in a decade.

Royal Bank of Scotland is the parent group of Ulster Bank here.
