A veteran Barclays executive involved in the Libor-rate rigging scandal has been made head of the bank's market operations in Asia Pacific, its second big markets appointment in a month.

The UK bank has named Mark Dearlove as head of markets for Asia Pacific, according to a memo sent to staff on Tuesday that was seen by Financial News. Dearlove replaces Conor Brown, who is taking a sabbatical and is due to return to the bank in 2016, according to the memo. A Barclays spokeswoman confirmed the appointment.
