Tesco chief executive Dave Lewis leaves an office, after the announcement of the company's interim results, in the City of London October 23, 2014. The chairman of Britain's biggest grocery chain, Tesco, announced his resignation on Thursday after the company reported a bigger than expected hole in its finances and said accounting transgressions went back further than initially thought. New chief executive Dave Lewis, just seven weeks into the job, said he could no longer provide a full-year profit forecast because he did not know the full scale of Tesco's problems or how much it would cost to rebuild the firm.
