The FCA Practitioner Panel is to be chaired by Alison Brittain, group director of retail, Lloyds Banking Group while the FCA Markets Practitioner Panel will be headed by Robert Mass, head of international compliance and global head of securities division compliance at Goldman Sachs.
The panels are independent statutory bodies that represent the interests of the financial services industry within the UK's regulatory framework.
FCA chairman John Griffith-Jones said: "These appointments ensure that once again the panels will have experienced and respected voices making the case from the industry's perspective.
"The current regulatory framework depends on the panels being able to play their part and I am sure that the new chairs will continue the excellent work of their predecessors.
"I would like to thank Graham, Paul and Andrew for their contributions over the last two years which oversaw the establishment of the FCA."
Panel members are recruited to represent sectors and the industry as a whole, rather than individual firms.
They are part of the system that the FCA set up to make and maintain effective arrangements for consulting practitioners and consumers on the extent to which its general policies and practices are consistent with its general duties, as set out in the Financial Services and Markets Act 2000.
