Barclays chief executive of mortgages Steve Weston is set to leave his role later this month.
Weston, who joined the lender as managing director of the bank’s retail division in 2012, is heading back to his native Australia.
A permanent replacement has not yet been found.
A Barclays spokesman says: “Steve Weston, CEO of mortgages, has decided to leave Barclays at the end of December to return back home to Australia with his family.
“Steve has played a crucial role in shaping the mortgage business to be a leading and innovative lender, and we wish him and his family all of the very best for the future.”
