Primark parent company Associated British Foods has announced that its chairman Charles Sinclair will retire and will be succeeded by Michael McLintock.
Sinclair will step down on April 11, after a tenure that saw the firm perform strongly since he was appointed to the role in April 2009.
He first joined AB Foods as a non-executive director in October 2008.
McLintock, who joined AB Foods last November as an independent non-executive director, is a former chief executive of fund manager M&G.
He will also succeed Sinclair as chairman of the nomination committee.
Meanwhile, independent non-executive director Ruth Cairnie will become chair of the remuneration committee.
The firm – which also owns the likes of Patak’s, Kingsmill and Twinings – is majority-owned by the family of chief executive George Weston.
It is due to release a trading update on Monday.
