The Royal Bank of Scotland's (RBS) director of group legal services Mark Chidley is leaving after just three years with the bank.
It is understood that Chidley, who replaced Derek Arnott in 2002, has not secured a position elsewhere.
Prior to joining RBS, Chidley was a partner at Addleshaw Booth & Co (now Addleshaw Goddard) for 18 years. During that time, Chidley launched the legacy firm's banking practice in 1998 and enjoyed a spell as national head of banking.
Commenting on Chidley's departure, a spokesperson for RBS said: "Mark Chidley has decided to pursue opportunities outside the RBS group. We thank Mark for the work he has undertaken for the past three years and wish him every success in the future."
It is understood that RBS will now look to replace Chidley. The bank's legal function is headed by Edinburgh-based general counsel Miller McLean, who is supported out of London by Leonie Fleming, the head of RBS's corporate banking and structured products team.
Chidley could not be contacted for comment at the time of going to press.
