Reform and Europe
No referendums took place between 1979 and 1997. During much of the 1980s the idea of using this device failed to attract the level of interest it had in some earlier periods. But, in the following decade, the referendum began to gain currency once more. After Labour returned to office in 1997, the Tony Blair administration became the most extensive utilizer of the mechanism to date, holding five in total (though none at UK level). Reflecting the establishment of the referendum as a firmer part of the UK constitution, a more consistent framework for this practice was introduced. After 2004, the Labour governments did not use referendums again. However, the device returned from 2011. During the tenure of David Cameron, as Prime Minister in a coalition (2010–2015) and then a Conservative administration (2015–2016), four referendums were held.
