The Financial Conduct Authority (FCA) has promoted its acting chief operating officer (COO) Nausicaa Delfas to executive director of international, responsible for delivering the regulator's response to the Brexit process.
This will include providing technical support to HM Government, working closely with the European Union, international regulators and the financial services industry to ensure a smooth Brexit transition.
In the newly-created role, Delfas will be responsible for growing the FCA's strategy for international engagement, which means leading relationships with foreign regulators and governments and enabling the FCA's work to shape the global regulatory agenda.
She will report to FCA chief executive Andrew Bailey and continue to sit on the regulator's executive committee.
Delfas has been acting COO at the FCA since November 2016. Prior to that, she held a number of roles at the Financial Services Authority (FCA) in the supervision, risk and policy divisions.
Bailey said: "This is a new and vital role for the FCA, reinforcing our focus on the global regulatory agenda, and importance of international co-operation. It is also critical for our work throughout the process of EU withdrawal.
"I would also like to welcome back Georgina Philippou to her role as COO after a period of extended leave."
Delfas added: "I look forward to leading the FCA's strategy for international engagement and working closely with colleagues in the international regulatory community, and the financial services industry.
"The work which we do internationally is vital to the delivery of our objectives, and it has become increasingly important given the UK's withdrawal from the EU."
The FCA has already hired additional general and legal staff ahead of what Bailey called a "tight" Brexit deadline.
