Donald Trump has announced that the new US secretary of state will be Exxon Mobil CEO Rex Tillerson.<br /><br /> Tillerson is a controversial choice as he set up billions of dollars of deals with Russia that can be executed only if the US lifts sanctions imposed over Vladimir Putin’s actions in Ukraine.<br /><br /> Tillerson was granted the Russian Order of Friendship in 2013 and has been criticised by senators over his relationship with Putin.<br /><br /> Environmentalists will also be concerned by the presence of an oilman at the top of the government, especially given Trump’s known scepticism about global warming.<br />
