Cameron has already handed close ally Dan Ritterband a key role as campaign director. Ritterband is an ex-ad man and was a member of Cameron’s Tory leadership bid team.
Now, Cameron is poised to tighten his grip on the campaign, according to senior Conservative sources. Favourite to be given a key job managing Johnson’s image is James McGrath, adviser to shadow chancellor George Osborne. But McGrath told PRWeek he had no plans to work on the campaign.
Last weekend’s Sunday Mirror pictured Johnson chatting on his mobile while driving on the motorway.
