CAIRO (Reuters) - The speaker of the eastern-based Libyan parliament, Aguila Saleh, submitted papers on Saturday to stand in presidential elections.

       The elections, scheduled for Dec. 24, remain in doubt amid disputes over the rules.

       "I came today to the headquarters of the High Elections Commission in Benghazi to submit the required documents for the nomination to the position of president of the Libyan Republic", he said on Libya Votes TV.
