MG Rover is to unveil a series of new saloon cars on Tuesday at the Longbridge plant before around 150 of the world's media.

The event is billed as a preview of the MG brand and product strategy with Kevin Howe, chief executive MG Rover, John Parkinson, sales and marketing director, Rob Oldaker, product development director and Peter Stevens, product design director in attendance.

Models on show are expected to be a high-powered Rover 75, MG X10 sport saloon first shown last November and re-badged and enhanced versions of the Rover 25 and 45 - all products of a £150m investment by MG Rover to improve the brand image.
