Willans has been at Mazars for five and a half years.
He says: “After five and a half years as CEO/CIO of Mazars Financial Planning, I have decided that it is now time to take a break and to consider new challenges and opportunities.
“I have, therefore, resigned from Mazars and will formally leave the business on June 1.”
He adds: “The next few years will see financial planning truly emerge as a new profession, and I am looking forward to continuing to play an active part in this.
“However, for the next few months, I am looking forward to the skiing season and cycling in Richmond Park.”
