Liam Fox was a GP before becoming MP for Woodspring in 1992. He was a minister at the Foreign Office for the last year of the Major government.
In opposition Dr Fox has been Shadow Health Secretary, Party Chairman, Shadow Foreign Secretary and is now Shadow Defence Secretary.
He contested the Tory leadership last year and emphasised leaving the EPP, supporting the war in Iraq, human rights and mending Britain's broken society. He was eliminated from the contest to succeed Michael Howard in the second round of voting amongst Tory MPs.
Last December he married Dr Jesme Baird, director of patient care at the Roy Castle Foundation.
He recently used an interview with GMTV to state that the Conservative Party must balance its new emphasis on green and justice issues with "traditional Conservative policies of wealth creation and of national security and of being tough of crime and so on".
