Diary: Turkey of the week - M&C Saatchi/Transport for London

Katherine Levy is frustrated by Transport for London's new Tube campaign by M&C Saatchi, which aims to drive traffic to the TfL website for answers:

"'Tube or false' is not only an irritatingly twee pun for the strapline, but it veers between the banal (who cares if the ghost of actor William Terris is or isn't said to haunt Covent Garden station. Just tell us) and the baffling: 'The fictitious EastEnders station Walford East is on the District Line' - well, if it's fictitious, it can't be, can it? Again, what? Who cares?"
