open Falkirk inquiry in wake of Grangemouth row David Cameron has backed a call from former Labour foreign secretary Jack Straw for the party to reopen its investigation into claims of union interference with candidate selection in Falkirk - which has links to the recent Grangemouth refinery dispute. The Unite official involved in the row, Stephen Deans, worked at Grangemouth for about 25 years and was suspended by Ineos over claims he used company time for political campaigning work. The original Labour investigation cleared Unite and its members of any wrongdoing after key witnesses withdrew their allegations.
