but AFAIK BA has 25% holding</font>
BA used to have a 25% holding but this was diluted to approx. 19% as BA chose not to exercise its option to buy shares in QF during the last stock offering. BA is generally considered to have a controlling interest in QF (though some might say that with the Eddington as BA CEO it is QF who has a controlling interest in BA).
