Huntley joins on 20 June to replace Sarah Kennedy, wife of the Liberal Democrat leader, in the beefed-up role of head of policy and public affairs.
She will report to director of corporate affairs Mark Gallagher, whom it was announced this week is to join the Camelot board, reflecting an increased emphasis on comms ahead of the effort to renew its licence.
Huntley has been with AS Biss & Co since 1999, and is currently head of client service and strategy. Her work includes leading the consultancy's account on London's Crossrail project.
While Camelot retains AS Biss for PA advice, Huntley has not worked on the account. Gallagher said her experience of working on gambling, consumer protection and government procurement issues for a number of other clients helped secure her the role.
'Lynette's role will encompass a more proactive campaigning element, which is a departure for the main Camelot public affairs job and fits in with our quest for a third lottery licence,' said Gallagher. She will oversee three PA staff.
Gallagher has rejigged the 22-strong comms team ahead of the licence battle. Teletext PR manager Kathryn Williamson rejoins next month as head of press and publicity, responsible for winners' PR. She left Camelot as consumer PR manager in 2003.
She replaces Liz Warner, who has been made head of special projects to exploit partnerships, such as with London 2012, and to publicise the work of the Camelot Foundation grant trust. Media relations manager Ben Rosier has been promoted to head of media relations.
Camelot this week announced a £150m growth in lottery ticket sales and that Dianne Thompson is to remain CEO.
