A combined UN civilian and peace-keeping force called UNTAG (United Nations Transition Assistance Group) under Finnish diplomat Martti Ahtisaari was deployed from April 1989 to March 1990 to monitor the peace process, elections and supervise military withdrawals. As UNTAG began to deploy peacekeepers, military observers, police, and political workers, hostilities were briefly renewed on the day the transition process was supposed to begin. After a new round of negotiations, a second date was set and the elections process began in earnest. After the return of SWAPO exiles (over 46,000 exiles), Namibia's first one-person one-vote elections for the constitutional assembly took place in November 1989. The official election slogan was "Free and Fair Elections". This was won by SWAPO although it did not gain the two-thirds majority it had hoped for; the South African-backed Democratic Turnhalle Alliance (DTA) became the official opposition. The elections were peaceful and declared free and fair.
