when did uk decide not to join euro
United Kingdom and the euro The United Kingdom has never sought to adopt the euro as its official currency for the duration of its membership of the EU, and secured an opt-out at the euro's creation via the Maastricht Treaty in 1992. Polls have shown that the majority of British people have been against adopting the euro, and in a June 2016 referendum the UK voted to withdraw from the European Union which would virtually eliminate the chance of any future adoption. Despite never being a member of the euro, the currency is used in the UK's Cypriot territories and as a secondary currency in Gibraltar, furthermore London is home to the majority of the euro's clearing houses.[1]
