Casofsky is to join at the end of the August; the role is currently held on an interim basis by Damien Drumm following the departure of Michael Salter-Church in May.
The move comes as the supermarket giant prepares to restructure its comms operation following the imminent departure of corporate affairs director Louise Evans. PRWeek reported earlier this week that Evans has been made redundant and is set to leave on 29 July.
Reporting to Judith Batchelar, director of Sainsbury’s Brand, Casofsky will oversee all public affairs activities for the group, including the Sainsbury’s grocery business, Sainsbury’s Bank, Argos, Argos Financial Services and Habitat.
Casofsky joined McDonald’s UK in 2006 and has led the public affairs function since 2010. He previously worked for Alan Hurst MP (2001 to 2002) and the Director General for Trade of the European Commission (2001). He also spent three years at Finsbury (2003 to 2006).
Since 2012, Casofsky has been chairman of the British Retail Consortium Corporate Affairs Strategy Group.
Batchelar said: "We look forward to welcoming Richard at such an important time for the retail sector. His experience of policy-making both at home and in the EU adds further strength to a talented team."
Casofsky said: "As a customer I’ve always admired Sainsbury’s. Sainsbury’s is an industry leader and now with Argos and Habitat has a great story to tell. I look forward to working with Judith and the wider team, and to contributing to the business’s success."
