Barclays is axing 1,800 IT jobs in the UK as it seeks to build "centres of excellence" in offshore locations.
The move was mooted at the beginning of this year, with the bank saying it informed staff in January about its plans.
Staff at Barclays' global infrastructure and service delivery (GISD) unit expect to see many of their jobs move to India, Hungary and Singapore.
It is believed around 700 of the 1,800 UK permanent and temporary jobs to go will disappear by September. Another 1,100 are set to go by 2010.
Around 1,000 GISD jobs are expected to stay at UK locations in London and Cheshire.
Barclays announced that 1,100 jobs would go at its IT processing plant in Poole, Dorset last year, and recently announced a round of customer contact centre job cuts across the UK.
Barclays said of the latest round of IT cuts, "we need to become fully global, with centrally managed technologies in centres of excellence in key locations around the globe".
The company added, "As far as possible, we will manage the reduction in headcount by reducing the number of contractors and temps we employ."
