Qatar invested £4.6bn and a further £7bn in the bank, in June and November 2008, respectively, which helped the lender to avoid UK government’s bailout.

Previously, the FCA threatened to £50m fine for violating certain disclosure-related rules over the advisory services agreement with Qatar.
Opposing the penalty, the bank said that the advisory fees needs not to be disclosed under the FCA rules and regulations.
Most recently, the bank agreed with the US regulators to pay a fine of nearly $36.1m to settle the charges for its involvement in financing, purchasing, and securitizing residential loans that were possibly unfair.
