Several powerbrokers in the NSW Liberal party have been asked to resign from its state council, in the latest push to remove professional lobbyists from positions of influence.

NSW Liberal state director Chris Stone wrote to representatives of Liberal-aligned firms who are also state council delegates shortly after former prime minister Tony Abbott complained about conflicts of interest during an interview with ABC TV's Four Corners.

The request has been sent to left faction powerbroker Michael Photios and centre right faction boss Nick Campbell, who jointly own lobbying firms PremierState and CapitalHill Advisory.
