Considered by some as the Brexit group most likely to be designated by the Electoral Commission as the official 'out' campaign for June's EU referendum, Vote Leave began searching for six PR firms and two creative agencies late last year.
Five of those PR firms have been appointed and began work earlier this month liaising with regional and local media, but PRWeek understands the campaign has found it harder to find an agency in the South East.
The process of looking for the two creative agencies continues and is expected to be completed shortly.
When asked by PRWeek who the five PR agencies were, Vote Leave said that only two had agreed to have their names published – Cool Blue Brand Communications, an integrated agency that is handling the North East and Yorkshire region; and creative marketing agency Trebuchet, which is handling East of England PR.
Tanya Garland, managing director of Cool Blue, which has offices in Newcastle, Middlesbrough and London, said: "As a company with no political affiliations it is really interesting to work on the Vote Leave campaign and to watch as the drama of the arguments and counter arguments unfolds.
"A major part of our role is to generate discussion and invite people who think they already know what they believe to open their minds and really consider the issues and how they might affect them."
Sue Wilcock, PR and marketing director of Ipswich's Trebuchet, said: "It’s great to be working on a campaign that will have an effect on every person living in the UK.
"What really helps is that the central team in London are able to feed us with timely and interesting copy that we are able to adapt to suit the media in our region. They also trust us to use our experience with journalists at grassroots level to identify initiatives and ideas that will gain the biggest pick-up; a great collaborative effort that gets the best results."
