The former AMP financial planner responsible for publicly airing damning allegations about high-pressure sales tactics at the company, resigned from the wealth manager under a cloud after it red-flagged some of his advice over compliance concerns.

Brett Strong, a self-employed financial planner who became an authorised representative of AMP in mid-2013, told ABC TV's Four Corners he was pushed to sell AMP financial products over other more suitable products offered by other institutions.
