In this capacity Robb worked with the next Leader of the Liberal Party, John Hewson, in the unsuccessful 1993 federal election campaign. Robb claimed in 1991 that Peter Reith and Hewson were spooked into releasing their policies too early. Robb was still Federal director when internal Liberal party negative polling was leaked to Kerry O'Brien on Lateline in May 1994 who embarrassed John Hewson with it and lead to Hewson's calling a leadership spill where he lost the leadership to Alexander Downer.
