Revell has worked at AMI in the field of policy analysis for the past five years.
AMI is looking to hire a new senior policy analyst, while they are interested hearing from individuals with a background in compliance, or mortgages, or public policy.
Robert Sinclair, chief executive of AMI, said: “This is the third AMI policy person who has left to join the regulator.
“I am delighted for Alex who has grown during his time with AMI and know that he will continue to champion the right thing for consumers as he develops his career.
“Alex will be missed by the whole AMI family, but the knowledge he takes to the FCA will benefit the wider industry.
“This also gives us the opportunity to recruit a new senior policy analyst to ensure that the intermediary broker market is professionally represented as we absorb the challenges of the new consumer credit regime and the European mortgage directive.”
