The story of the 2014 European elections in the UK is slightly more exciting than the words 'elections' and 'European' would automatically suggest.
As with the Scottish, Northern Irish, Welsh and London Assemblies, the electoral system used for European elections in the UK is the Single Transferable Vote, or STV. This is a system of proportional representation whereby the voter lists the candidates in the order of their preference, and then maths and random chance do some magic, at the end of which you get some people elected. It is also used in Ireland, Malta and Australia, but without the work of one individual, it would not currently be used in Britain.
This individual was Michael Meadowcroft, a former Liberal MP who founded his own 'continuity' Liberal Party in protest at the original Liberal Party's merger with the Social Democrats. He and his band of followers performed terribly in by-elections in the first few years of their existence, but to the surprise of almost all concerned, Meadowcroft won back his old seat of Leeds West in the 1992 general election - and this was a fortuitous time to be a minor party MP, for John Major had only won a minority of the seats in the Commons, and needed the support of several other parties in order to govern. The Lib Dems turned him down, but offers of extra funding for Northern Ireland won over the UUP and DUP, a referendum on Scottish and Welsh devolution won over the SNP and Plaid Cymru, and a referendum on Maastricht kept his own backbenchers in line over the tumultuous parliament of 1992-1996 - all of those referendums, of course, failed to be passed. One more vote was needed to pass the Queen's Speech: Meadowcroft's. And Meadowcroft merely demanded the institution of STV for the European Parliament - the rest of Europe wanted to work towards a one-size-fits-all electoral system across the continent, and Britain's antiquated use of FPTP for electing MEPs was the subject of much weeping within the salons of Strasbourg.
Major acquiesced, and STV was established as the go-to form of PR in the UK, with the Jenkins Commission going by the precedent of 1992 when recommending electoral systems to the reforming Blair Government of 1996-2005. However, Alun Michael took the piss a little bit by establishing that the constituencies used for the new Welsh Assembly in 1998 would have two members each. Elsewhere, the constituencies would have between three and five members.
Meanwhile, Meadowcroft had failed to be elected for Yorkshire North in the 1994 European elections, although he won a seat in Italy for the libertarian Pannella List, an experience which influenced his later career somewhat: he differentiated himself from the Lib Dems by identifying closely with sexual liberation movements and the liberalisation of drug laws. He also spent quite a bit of time commuting between Leeds, London, Brussels and Italy. The latter proved popular in Leeds West, where he was re-elected in 1996. In fact, he was joined in that election by Steve Radford in Liverpool West Derby and Terry Milson in Bethnal Green and Bow, although Milson was later expelled from the Party and the seat was regained by Labour in 2000, never to be lost again. Meadowcroft remained in the European Parliament in 1999, this time for his own party (dubbed 'Meadowcroft's List - The Liberals' despite the fact that Lists aren't really a thing in STV) in the constituency of Rheged, which encompasses Radford's stamping ground in Liverpool.
Meadowcroft also lost his Westminster seat in 2000, (which was convenient, given that double-jobbing laws were introduced in Europe in 2004) although Fran Oborski won Wyre Forest in the context of a major campaign against the closure of the Kidderminster A&E unit, to join Radford in the Commons. Radford's star was rising: slightly more left-wing than Meadowcroft and with a broad network within the minuscule party, he gained exposure with some cringeworthy appearances on BBC's satirical current affairs flagship The News Quiz, and by the time of the 2004 Euro elections, the name of the party had changed to 'Meadowcroft-Radford List'. Off the back of Fran Oborski's win in 2000, Rob Wheway was sent to Brussels from the three-seat Mercia constituency in this year. The next year, Radford had ousted Meadowcroft (who had been a pupper leader for some time and was, perhaps unfairly, blamed for some unpleasantness emanating from Edinburgh) and the party was renamed 'Radford's Liberals'. Both Radford and Oborski were re-elected, and Meadowcroft remained largely quiet on the Green-EFA benches in Brussels until 2009, apart from one occasion when he engaged in a fistfight with Ian Paisley while the Pope addressed the Parliament.
Oborski lost her seat to the all-conquering Labour Party in 2010, after five years of opposing the Hague government, and later rejoined the Liberal Democrats. Radford also lost to Labour in 2015, his divisive personality and lack of policy differentiation from the Lib Dems having proved his Achilles heel: he had tried to differentiate the party by renaming it the 'Radical Party' in 2010 after the Lib Dems had gone into coalition with Theresa May, but it didn't help him. However, the European seats were maintained: Hazel Williams held the Rheged seat until 2015, when she resigned and caused a by-election which Radford won, while Wheway was succeeded by Graham Ballinger in 2009. Ballinger left the party in 2016, amid a tumultuous internal struggle between Radfordites and Libertarians, with the latter eventually replacing Radford as leader with Oliver Wainwright and helping Loz Kaye to win the Manchester Gorton by-election of 2017, in a resounding re-entry to the Commons for the Radical Party.
Thus, the 2014 Euros proved that there was still a bit of life in the Radical Party, but that it needed to be refreshed if it was to remain relevant. Meanwhile, the Liberal Democrats lost almost all of their seats due to blowback from the coalition - a collapse which allowed Nigel Farage, Robert Kilroy-Silk and Stuart Agnew to take the UKIP's first seats in any Parliament. The first Green MEP, Derek Wall, was another beneficiary of the decline of Hughes' party.
Finally, only winning 25 seats out of 73, John McDonnell was forced to resign as Leader of the Labour Party after just four years, which allowed the hitherto unknown Liz Kendall to turn the party's fortunes around and win the 2015 general election with a landslide, including a manifesto promise to take Britain into the Euro. Things are looking up for the UK as an EU member state, despite Denmark voting to leave the union in 2016.
