Brown joins the organisation’s board for a three-year term, working with chief executive Stephen Woodford and president Keith Weed.

Part of her focus as chair will be to support the AA’s work to address declining public trust in advertising, as highlighted in its recent report. She will report to the board on behalf of the AA’s advertiser, agency and media members.

Murphy, co-founder of Adam&EveDDB, has completed an extended tenure at the industry body to support its work around Brexit. He will take on a newly created role as the AA’s export champion, leading efforts to grow exports of UK advertising services internationally.

Woodford said: “Philippa brings unrivalled management experience from both the agency and publishing worlds and I am looking forward to working closely with her, Keith and our AA Board and Council as we implement our plan to address the decline in public trust in advertising.”

He added: “I am pleased that James is staying on in a new role, supporting our exports programme to help keep the UK as the foremost global centre for advertising.”
