This paper provides a critical theoretical review of the political factors, which significantly influenced the June 2016 Brexit decision to leave the European Union (EU). This paper also provides a critical investigation of the likely impact of Brexit on certain social, political and economic aspects of the UK landscape. To this end the paper also analyses the effect EU policies on theeconomy, migration, sovereignty and democracy had on Brexit views. During the 2014 European Parliament elections, the UK Conservative Party haemorrhaged electoral support to the United Kingdom Independence Party (UKIP). During the 2016 Brexit Referendum campaign, the ruling elite had an unfounded expectation that UK citizens would vote to remain in the EU. Under the policy vacuum of no change, the political mantra of UKIP became appealing to an increasing majority in the UK. The failure to ensure that UK citizens were informed of the finalised EU-UK Brexit deal before the referendum took place (as indicated in David Cameron’s 2013 Bloomberg speech) will prove to be telling. By August 2018, the rationale that a second referendum should be held was overwhelming. The UK population will experience many of the significant elements of the political threats, which were made during ‘project fear’. The reality of post Brexit for many UK people will be quite different to the panacea they envisaged.
