Lloyds TSB will cut 2,100 jobs, in a move set to hit IT and back office roles.
The announcement, which will also affect staff in its business banking division, states that the jobs will go over the next three years, and follows on from 965 cuts announced in April.
Lloyds TSB is combining operational support functions with those of HBOS, with which the group merged in 2008. It is also combining Lloyds TSB and HBOS business banking divisions.
The new job cuts are part of a review that took place last year within HBOS, in which Lloyds Group announced plans to cut £1.5 billion from overhead costs over the next three years. Media reports suggested cost savings would come from streamlining IT support and mortgage processing.
A spokesperson at Lloyds TSB declined to comment on how many IT jobs would be lost. But the company said it would not "offshore any further permanent existing operational roles".
The Lloyds TSB Union reacted with anger at the news, saying the bank should "invest in UK jobs" instead of offshoring.
