The pain never ends at Royal Bank of Scotland. The bank, still 81%-owned by the UK government, said late Monday it would take more than £3 billion of extra provisions for various legal issues and past misconduct claims.

That puts RBS on course for a huge loss in the last quarter of 2013. The bank had already said it would take an impairment charge of £4 billion to £4.5 billion as result of its plan to set up an internal "bad bank" to deal with problem assets left over from the financial crisis.
