Businessman Declan Ganley - who billionaire Denis O'Brien believes is allegedly behind a lobbying campaign designed to damage him - has failed in a High Court application to have certain claims in the case determined before the main trial involving a public relations firm.

Mr O'Brien is suing the Red Flag Consulting public relations firm and a number of people involved in it, along with Mr Ganley who has interests in the telecommunications business.
