The party of Myanmar opposition leader Aung San Suu Kyi has requested a change in the wording of the oath that lawmakers have to take, presenting a potential hurdle to her taking up the parliamentary seat she won this month.

The National League for Democracy has asked the authorities to adjust the wording of the oath to say that parliamentarians will "abide by the law" rather than "protect the constitution," Nyan Win, a spokesman for the party, said Wednesday.

Suu Kyi's party won 43 of the 44 seats it contested in by-elections on April 1. She is scheduled to attend her first session of parliament on Monday after she was elected in the constituency of Kawhmu.

Nyan Win said the NLD was waiting for Myanmar authorities to respond to the request. He declined to say what Suu Kyi and the other elected members of the party would do if the oath wasn't changed before the parliament session began.

News of the complication emerged as Norway announced that Suu Kyi would visit the country in June, her first overseas trip since she was released from decades of house arrest in 2010.
