In 1962, Jago was elected the member for Gordon in the
New South Wales Legislative Assembly. On the election of the
Askin government he became Minister for Health and he held that position until he left parliament. In the lead-up to the 1973 election Jago failed to lodge his nomination for the seat of Gordon before the closure of nominations. As a result, in order to prevent the
Labor candidate from winning, most Liberal Party voters supported the
Democratic Labor Party candidate
Kevin Harrold, who therefore had an unexpected victory. Jago died in the Sydney suburb of
Killara in 1997. ==References==
