The appointment comes less than a month after GUS announced that its executive chairman Lord Wolfson planned to retire earlier than expected.
Stocken is also a non-executive director of property company MEPC, leisure to hotels group Rank, glass manufacturer Pilkington and chairman of Rutland and of Lupus Capital.
Stocken was finally given the green light to retire from Barclays in September last year following the appointment of David Allvey as finance director. He had twice deferred his retirement while the bank tried to find a suitable successor.
Since he joined Barclays Merchant Bank in 1979, Stocken held a number of senior positions in BZW before joining the board in 1993 as finance director.
