City Diary: Goldman Sachs overstates its call on ICAP departure Swann song for WH Smith's Kate Interesting to see that M&S high-fliers include former WH Smith stalwarts Alan Stewart (finance director 2005-2008) and Tanith Dodge (HR director 2003-2008). Could outgoing WH Smith chief Kate Swann be next to follow the well-trodden path? Job offers are expected to come thick and fast for Swann when she steps down next summer - but those in know say the chance to rejoin familiar faces could tip the balance in M&S chairman Robert Swannell's favour... G4S's logical operating systems How the telephone operating systems work at G4S. If you have a job, or employment enquiry, please press 1. Diary did so, keen to find out more about the vacancy for a Bid Manager in the firm's Risk Management division - an exciting role that involves pitching for new security contracts for the FTSE 100 firm. But the G4S computer said no, alas, since all information on advertised jobs was wiped from the system when the online careers portal went live. "I can't give you the information, madam, if I don't have it," hung up the operator with faultless logic. Meanwhile, G4S explained it was "entirely appropriate" to throw a country house party complete with smoked duck and fillet steak at the weekend, because none of the 300 staff invited had been "involved in the Olympics." "We do not believe these highly deserving employees, who include a security officer who prevented a mentally ill patient from committing suicide, or two rugby stewards who were the first on scene to help victims of a major road accident, should be penalised for issues elsewhere within the company," said a G4S spokesman, as caterers at Whittlebury Hall near Towcester swept up the champagne corks. Last past the post A postscript on Diary's story last Friday on alleged insider dealer Iraj Parvizi's racehorse running in the Queen Elizabeth II Stakes at Ascot on Saturday. Or should that be a last-past-the-postscript? Nag Most Improved failed to live up to its name, says my man at the finishing line - the horse "tailed off" to hobble home in last place. Apparently, the final furlongs put him away for a long stretch.
