The FCA has hired former Investment Association chief executive Daniel Godfrey on a consultancy basis.
Godfrey, who was ousted from the investment industry trade body last year, will join the regulator to work in the asset management policy team, rather than in a decision-making capacity.
The FCA was not able to give details of the policy Godfrey will be working on or the length of his contract.
Godfrey was forced to resign from the Investment Association last year, after a number of high-profile members threatened to quit.
Since his departure he has been vocal on the need for the asset management industry to reform, including focusing on fund manager pay and the transparency of fund charges.
