Mark Bailie, head of Royal Bank of Scotland Group PLC's digital lender, Bó, is expected to leave the company as part of a management shake-up overseen by the British lender's CEO, Alison Rose, Sky News reported.

According to sources, Bailie's departure will potentially be disclosed alongside or before RBS announces its full-year 2019 results on Feb. 14.

Bailie, who served as COO at RBS before taking on responsibility for developing Bó, was viewed as a potential rival to Rose for the CEO post at the group.

The news comes as Rose prepares to make further changes to RBS' senior leadership team, people close to the matter said. The bank is in the process of identifying a successor for its CEO of personal banking, Les Matheson, while its chief marketing officer, David Wheldon, is expected to retire in 2020, Sky News added.

The changes are expected to help Rose shape the bank's top team before Chairman Howard Davies steps down, according to the report.
