euro was maastricht 1992 and more complex as markets pretty much decided uk couldnt stay in ERM and was never seriously on the cards after
The United Kingdom entered the ERM in October 1990. The UK government spent over £6 billion trying to keep its currency within the narrow limits prescribed by ERM, but was forced to exit the programme within two years after its currency the pound sterling came under major pressure from currency speculators. The ensuing crash of 16 September 1992 was subsequently dubbed "Black Wednesday". During the negotiations of the Maastricht Treaty of 1992 the UK secured an opt-out from adopting the euro.[137] The Labour government of Tony Blair argued that the UK should join the euro, contingent on approval in a referendum, if five economic tests were met. The UK Treasury first assessed tests in October 1997, when it was decided that the UK economy was neither sufficiently converged with that of the rest of the EU, nor sufficiently flexible, to justify a recommendation of membership at that time. The assessment of June 2003 concluded that not all were met.[138] The Conservative-Liberal Democrat coalition government elected in 2010 pledged not to join the euro during its term of office,[139][140] due to expire in 2015.
