==you can't be serious== 
 Tongue in cheek, Charles de Gaulle twice suggested that France [citation needed], although it was never a member of the British Empire (even if the Duke of Normandy conquered England and English/British monarchs claimed the title 'King of France' for centuries ), WTF? this paragraph is unsourced absurd statement isn't? the first half of the claiming states that France could had been part of the British Commonwealth even though it was never member of the Empire and the second half says "the British were part of the French Kingdom"?? iy doesn't make sense at all and there is no source for De de Gaulle's quote.
