SARAJEVO, Aug 11 (Reuters) Slovenia, a member of the euro zone, will hold a presidential election on Oct. 22, parliament speaker Milan Brglez said today. Slovenia's president has a mostly ceremonial role but is head of the army. President Borut Pahor has said he will seek re-election as an independent candidate and is expected to win another five-year term. "Slovenia needs a president who will hold features such as courage, principles, honesty, integrity and openness," Brglez, a member of the SMC party led by Prime Minister Miro Cerar, was quoted by the STA news agency as saying. He said he would not run for the post.
