ROME, Sept 29 (Reuters) - Italian Prime Minister Mario Draghi said on Wednesday an ongoing review of the European Union’s fiscal rules is almost sure to result in some changes. “It seems unrealistic to me to think that we will keep the same rules as before,” Draghi told reporters after a cabinet meeting in Rome. In other comments, Draghi said that recent events had shown “we need to spend much more on defence.” Reporting By Gavin Jones Our Standards: The Thomson Reuters Trust Principles.
