RBS may face full-year losses of up to £8bn, after the bank said it needed another £3.1bn for claims relating to the financial crisis.

Shares in the 80%-taxpayer owned bank dropped 3% on the news.

RBS boss Ross McEwan said the scale of bad decisions during the period of the financial crisis was to blame.
