LBG, which passed EU-wide bank stress tests at the weekend, is to shed about one-tenth of its workforce and shutting about 150 branches over the next three years, it said in a statement.
The bank said it had returned to profit in the third quarter, posting pre-tax earnings of 751 million pounds (USD 1.2 billion, 952 million euros) in the three months to the end of September compared with a loss of 440 million pounds in the equivalent period one year earlier.
The bank, which remains 25-percent owned by the British taxpayer, has meanwhile decided to cut its headcount by about one tenth with the loss of 9,000 jobs
This comes after it has already axed tens of thousands of staff since the 2008 financial crisis which triggered a multi-billion-pound state bailout of the lender.
"In order to make the Group more efficient, we expect to exit 2017 with a cost:income ratio of around 45 percent and are targeting reductions in each year of the plan," LBG said in a statement.
