US investment bank JP Morgan is facing a record fine of more than $13bn - some £8bn - to settle investigations into its mortgage-backed securities.

The potential settlement comes a month after the company was fined £1bn for the "London Whale" scandal, in which a former employee placed huge disastrous bets on the financial markets.
