Lawyers representing Ian Norris, the former chief executive of UK engineering group Morgan Crucible, are to lodge an appeal with the High Court after Friday's decision by the UK Home Secretary to order the businessman's extradition to the US.

The law firm, White & Case, will also press for its application for judicial review, granted in the summer, to be heard as soon as possible. It is attempting to prevent Norris's extradition to face charges of price-fixing and obstruction of justice under arrangements between the UK and the US that it regards as flawed and unfair.
