Liam Fox has been appointed Secretary of State for the new International Trade department, by new Prime Minister Theresa May.
Dr Fox, who ran against Ms May in the Conservative leadership race but fell out early on after a lack of support from Tory MPs, was a prominent Brexit supporter.
He served as Defence Secretary in the Coalition government, but was forced to quit in 2011 after it was revealed he gave access to the department to a friend.
The new International Trade department will hold a key position in government in the coming years as the UK leaves the European Union. With uncertainty around how the UK will trade with Europe and the rest of the world, the department will be at the forefront of efforts to make sure British businesses are selling themselves to a global market.
Liam Fox is likely to work closely with Boris Johnson, who was appointed Foreign Secretary by Theresa May, and Philip Hammond, who has replaced George Osborne as Chancellor of the Exchequer. He will also work closely with David Davis, who has been appointed Secretary of State for Exiting the EU - already dubbed 'Brexit Secretary'.
