The widow of a British soldier killed by American friendly fire has appealed directly to President George Bush for help in finding the truth about her husband's death. Lance Corporal Matty Hull died when his vehicle was attacked by US tankbuster planes in southern Iraq four years ago. His inquest was presented with more evidence from American authorities but some sections were blanked out. His wife Susan called on Mr Bush to release information blacked out of a US Friendly Fire Investigation Board Report.
