In 1983 the departments of Trade and Industry were reunited. The Department of Energy was re-merged back into the DTI in 1992, but various media-related functions transferred to the Department for National Heritage. Until it was disbanded in June 2007 the DTI continued to set the energy policy of the United Kingdom.
After the 2005 general election the DTI was renamed to the Department for Productivity, Energy and Industry[2], but the name reverted to Department of Trade and Industry less than a week later [3], after widespread derision, including some from the Confederation of British Industry.
The DTI had a wide range of responsibilities. There were ultimately nine main areas covered by the DTI: Company Law, Trade, Business Growth, Innovation, Employment Law, Regional Economic Development, Energy, Science, and Consumer Law. It also had responsibility for investigating misconduct by company directors, in which rĂ´le Private Eye repeatedly lampooned it as "the Department of Timidity and Inaction".
UK Trade and Investment[4]was a joint DTI/Foreign & Commonwealth organisation to help UK companies do business abroad and assist overseas investors to the UK.
