Career in national politics

Glos first became a member of the Bundestag in the 1976 elections, representing the Schweinfurt district. From 1993 to 2005 he was chairman of the CSU parliamentary group and deputy chairman of the CDU/CSU parliamentary group.

Following the 2005 elections, Glos was appointed as Federal Minister for Economic Affairs and Technology at short notice when CSU leader Edmund Stoiber rejected it.^[2] Merkel had reportedly wanted to appoint him as Federal Minister of Defence.^[3]

During his time in government, Glos was widely considered one of the weakest members of Chancellor Merkel's cabinet and had often seemed to struggle with his portfolio.^[4] Among other projects, he led efforts on a 2008 law that allows the government to block moves by foreign investors to take large stakes in German companies, if it concludes that they endanger the country's interests.^[5]

On 7 February 2009, Glos offered his resignation as minister, which was first denied by Horst Seehofer,^[6][7] but later accepted.^[8][9] He justified his resignation with his age and the need for renewal in the CSU after Seehofer's election as CSU chairman.^[10]
