NICOSIA – Cyprus’ parliamentary speaker has resigned after an undercover news report allegedly caught him on tape promising to help circumvent the country's rules on granting citizenship to foreign investors.Demetris Syllouris had initially decided to stay on as speaker but abstain from his duties until investigations ran their course.Syllouris, who had a 28-year record of service as a lawmaker, said Thursday he had not wanted to quit because it would appear as if he was guilty.“I maintain my resolute conviction that I did not violate the law in any way,” he said in a statement.The scandal erupted after news outlet Al Jazeera’s investigative unit used hidden cameras to show Syllouris and others promising to a man posing as a representative.
