Liam Byrne replacing Hazel Blears, one of the highest-profile roles in the government outside the cabinet. However, just a fortnight later Home Secretary John Reid moved him to the immigration role, switching portfolios with Tony McNulty. McNulty had been connected with the foreign prisoners scandal that caused Tony Blair to sack Charles Clarke in May 2006. Byrne's move was seen as an attempt by Reid to establish an entirely new team to sort out the immigration system. During this period he was also Minister for the West Midlands. Gordon Brown named him Minister for the Cabinet Office in October 2008, replacing the
United States Secretary of Defense 2,595 days. Combining his two non-sequential services as Secretary of Defense, the second longest serving is Donald Rumsfeld, who served just ten days fewer than McNamara. The shortest-serving Secretary of Defense is Elliot Richardson, who was quickly moved to US Attorney General after 114 days due to resignations during the Watergate Scandal (not counting Deputy Secretary of Defense William P. Clements and William Howard Taft IV, who each served a few weeks as temporary/acting Secretary of Defense). The Secretary of Defense is sixth in the presidential line of succession, following the Secretary of the Treasury and preceding the Attorney General.
