Read made the announcement on Twitter yesterday evening.
Just confirming I am standing down from the board of the PRCA.— Kevin Read (@ReadKevinRead) August 22, 2017
He had become a director of the trade body's board of management, an unpaid position, in October 2016.
PRCA director general Francis Ingham said: "We can confirm that Kevin Read has stood down from the Board of Management of the PRCA. We would like to thank Mr. Read for his contribution to the PRCA."
Kevin Read is currently on sabbatical from Bell Pottinger until October 2017, and is writing a book on the 'art of pitching'. Although he is the chair of Engage, the agency's new brand and consumer PR offering, he was absent from its launch event at the start of the year.
Bell Pottinger's chief executive James Henderson spent last Friday in a hearing with the PRCA over its highly controversial work with South African client Oakbay Investments.
