Its subsidiary, ESB International, is on the hunt for a replacement UK public affairs agency because FD represents rival firm Viridian. The brief involves PA and PR advice around its plans to build an 800-megawatt gas plant on the site of a former power station at Marchwood in Hampshire. It involves consultation with local authorities and complying with environmental regulations.
LLM was taken on for the task just seven months ago.
ESB group head of public affairs Eoghan O'Neachtain said: 'Because of a potential conflict of interest we will be seeking another public affairs consultancy.' He added it had been 'very pleased' with LLM's services.
FD announced its acquisition of LLM on 26 July. The agency's 23 London staff will move into FD's offices next month.
