"British American Tobacco is facing questions over whether it was involved in covertly lobbying MPs to persuade the government not to ban cigarettes from being displayed for sale in shops. It is under pressure to disclose whether it secretly funded a campaign against the plan instigated by the National Federation of Retail Newsagents (NFRN). The plan, which led to tensions in the coalition, involved efforts over many months by the London public affairs firm Hume Brophy to influence MPs and the media." (Quoted from article)
