In 1999, Burg returned to domestic politics, and was elected to the Knesset on Ehud Barak's One Israel list (an alliance of Labor, Meimad and Gesher). Although Prime Minister Barak backed another candidate, Burg was elected Speaker of the Knesset, a position he held until early 2003. In his capacity as speaker of the Knesset he served as interim President of Israel for 20 days, from 12 July until 1 August 2000 when the presidency was vacant following Ezer Weizman's resignation.
