Career
Armitage was comfortably reelected in the 1993 election as the Liberals swept to power in a landslide. Over the next nine years he held portfolios including Minister for Health, Minister for Aboriginal Affairs, Minister for Disability Services, Minister for Government Enterprises, Minister for Administrative and Information Services, Minister for Government Enterprises, Minister Assisting the Premier for Information Economy, Minister for Government Enterprises and Minister for Information Economy. Armitage was narrowly reelected in 1997.
After a redistribution ahead of the 2002 election made Adelaide even more marginal, Armitage tried to transfer to Bragg, the safest Liberal seat in Adelaide.
He was soundly defeated for Liberal preselection by Vickie Chapman. Meanwhile, his replacement as Liberal candidate in Adelaide, Deputy Mayor Michael Harbison, lost the seat to former Mayor Jane Lomax-Smith.
In 2005, he was appointed as Chief Executive Officer of the Australian Health Insurance Association.
