Bill Clinton’s 900-page memoir may not be a critical favorite, but it has been a runaway bestseller on both sides of the Atlantic. But critics recently noticed that the version of “My Life” being enjoyed by readers in the UK differs in several important respects from the stateside version. The changes, which are almost all in passages in which President Clinton pointedly criticizes Whitewater special prosecutor Kenneth Starr, are due to the differing libel laws in the two countries. Whereas the burden of proof in a libel case falls on the complainant in America, UK law forces the defendant to prove the veracity of contested statements, which Clinton’s people feared could have opened the door to a Starr lawsuit.
