An executive with Independent News and Media plc (INM) claims the company's major shareholder Denis O'Brien was behind an allegedly unlawful attempt to oust him.

Karl Brophy, director of corporate affairs and content development at INM, today sought a High Court order to prevent him from being dismissed.

This was refused by the court but a High Court injunction was granted restraining INM from acting further on its decision of May 8 to terminate his employment until a further hearing on Tuesday when INM will present evidence.

Mr Brophy also got an order restraining the company from releasing disseminating or divulging any confidential information in relation to his employment and its termination, the validity of which is disputed.

It includes communication through the internet and mobile phone text messaging.

The order is in place until next Tuesday.
