A "clean-up" plan announced by Royal Bank of Scotland will wipe £2.5 billion off its annual profit and push it into a loss for 2015, reports the BBC. In a statement, RBS said it was setting aside another £500 million to pay for PPI claims and £1.5 billion for US litigation. In addition, the 73 per cent taxpayer-backed bank will write down £498 million from its private bank Coutts. The bank is also speeding up a plan to make payments into its pension fund to help deal with a £4.2 billion deficit caused by a change in accounting standards. RBS has not made an annual profit for seven years and is due to report results on 26 February.
