Two former grocery heavyweights could be poised for a return to the industry.Richard Baker and Scott Wheway have left Alliance Boots following a shake up by its new owners, private equity firm Kohlberg Kravis Roberts and deputy chairman Stefano Pessina.

Baker, who was CEO of Alliance Boots, joined Asda in 1995 and was its chief operating officer between 2002 and 2003 when he joined Boots.

Wheway, who had been MD of Boots the Chemist since 2005, previously ran Tesco's Japanese operations.

He said he had left Boots because "his own career plans did not enable him to give a firm commitment to stay for the next few years", according to Alliance Boots.

Analysts said Wheway would probably look for a senior role in grocery retail, possibly at Morrisons or Somerfield, though not at Tesco "because there were no senior positions left". Baker would also be after a senior role, said one analyst, but might be more interested in a private equity business.
