‘We will introduce a United Kingdom Sovereignty Bill to make it clear that ultimate authority stays in this country, in our Parliament,’ the Conservative Party's 2010 manifesto said. It was a promise they never kept. Six years later it’s a promise that’s completely obsolete, thanks to the EU referendum, although just now even that ‘ultimate authority’ is in some doubt, as the Supreme Court deliberates on Miller v. The Secretary of State for Exiting the European Union. ‘Our approach to foreign affairs is based on a belief in freedom, human rights and democracy,’ the 2010 manifesto also said. ‘We are sceptical about grand utopian schemes to remake the world. We will work patiently with the grain of other societies, but we will always support liberal values.’
