Lloyds TSB has appointed Mark Fisher, executive director at Royal Bank of Scotland Group (RBS) and ABN Amro chairman, as its director of group IT and operations.

Formerly responsible for the manufacturing division at RBS and its activities including IT, property, purchasing and back-office services functions, Fisher will also become a member of Lloyds TSB's group executive committee when he joins next year.

Fisher's achievements at his former employer included carrying out the integration of NatWest when it was acquired by RBS in 2000, which included about 400 work streams, 22 billion records and 18 million customer accounts including £158bn in deposits.

"This appointment completes the strong leadership team that will drive our new group," said Lloyds TSB chief executive Eric Daniels.

"[Fisher] has a deep expertise in banking, and his proven track record in dealing with highly complex integration activity will be a great asset to the new Lloyds banking group."

The future at the merged bank of Darryl West, Lloyds TSB director of group IT, and Heather Jackson, HBOS chief information officer, is still uncertain.

"Nothing has been decided beyond the appointment of Fisher as director of group IT and operations," said a Lloyds TSB spokesman. "The process is being handled in stages and further decisions will be made over the next few weeks or months."
