How could a Parliamentary Assembly contribute to national democratization?

A Parliamentary Assembly would give a voice to representatives of national parliamentary opposition groups at the UN. Through their international office, opposition members would be in a better position to reach out to the international public. Their position in the home country would be strengthened and a restriction of their rights through the government would be made more difficult. For delegates close to autocratic governments, the experience of participating in an assembly and of cooperating with other delegates from democratic countries could set a powerful example and have a democratizing effect. In addition, the Parliamentary Assembly would strengthen the credibility of the UN in promoting national democratization.
