The UK election should be about trust, instead it will be about fear As expected, Ukip walked the Rochester and Strood byelection. Mark Reckless won Nigel Farage's party its second Westminster seat defeating Conservative candidate Kelly Tolhurst by 2,920 votes. Ukip took 42% of the vote, the Conservatives 35%. A 28% Conservative to Ukip swing. With 349 votes (0.9%), the Liberal Democrats recorded the party's worst ever result in a Westminster election, finishing fifth, behind the Greens" 4%. Labour dropped 12 points on their 2010 result, and ended up with 17% of the votes cast. Despite this poor result, the bar of expectation had been set so low by Labour, that for once Ed Miliband could have grabbed the popcorn and watched the spotlight turn on David Cameron - but his party was able to tweet its way into Friday morning's headlines. The next few months will be spent guessing who among the Tories" most rebellious MPs may defect next to Ukip. While many lean in to play Tory defection bingo, beneath their feet British politics is changing in unprecedented ways. The bigger party is taking place in another room. Recent polls show the combined support for Labour and the Conservatives on around 60% - down by about 10 points on January. In elections since 1979, Britain's two main parties won a combined 81%, 70%, 73%, 76%, 74%, 73%, 67%, and 65% in 2010. While the trend is clear, its depth is better highlighted once we take a step back to look at the changes among other parties. In 2010 for example, the Lib Dems won 23% of vote, leaving all other parties on a combined 12%. Recent polls have SNP, Ukip and the Greens, together above 25%. In 2010 the three parties won 6% of the vote. The fact is all the more remarkable considering that the SNP is a Scottish party, and both the Greens and Ukip don't even contest all seats. Figures released over the past month show the SNP is on course to winning nearly nine times more Westminster seats than all other parties in Scotland combined. Labour, which currently holds 41 seats north of the border, would all but be wiped off Scotland's electoral map. There is not only a rise in support for the "others," but there is also far greater fragmentation across the electorate. YouGov analysis has found that the proportion of Ukip voters coming from the Labour party has trebled since January 2013, from 7% to 23%. While this is still lower than Tory converts (36%), compared to earlier Ukip support, Nigel Farage's votes are now more widely distributed. Before the beginning of last year six out of every 10 Ukip votes came from the Conservatives. Similar trends are present in flows towards the Greens. More than 80% of the party's vote in 2015 will come from those who in 2010 supported other parties. Half of that support is coming from Lib Dem voters. Britain has gone from a two-three party system to a six party system The challenge is that the UK's voting system isn't designed for a multi-party system. Voting systems are a reflection of a country's political system, culture and history. An attempt to summarise these factors in a balance between governance and representativeness. In a landscape historically dominated by two parties, first-past-the-post works relatively well. But, once votes are more distributed across a much bigger number of parties the method is less efficient, and the representativeness gap widens. On 6%, but with say only one member of parliament, the Greens would win 40 times fewer seats than they would under proportional representation. There is of course an elephant in the room, which should not be ignored - Britons said no to changing the voting system in a 2011 referendum. Nevertheless, circumstances have changed over the past three years, and more importantly the representation gap matters if we look at the underlying reasons behind the fragmentation currently present in the country's electorate - a crisis of trust. Only 10% of UK voters believe that British politicians are out to do their best for their country. In 1972 the figure was 28%. It's not just Ed Miliband that is unpopular. All of Westminster's political leaders have negative ratings - more people are dissatisfied with party leaders than the number happy with Cameron, Clegg, Miliband - and Farage. 68% of Ukip voters would like to turn the clock back to the way Britain was 20-30 years ago. Conversely, in Scotland 65% of voters are satisfied with both First Minster Nicola Sturgeon and her predecessor Alex Salmond. Instead of tackling the trust deficit, the main parties are turning the election into a contest about fear - and what voters should be frightened of most. Labour warns of the imminent collapse of the NHS. The Conservatives of an impending global financial crisis. Ukip had claimed that hundreds of thousands of Romanians were heading for these shores. Millions of Romanians did queue a week ago - often for hours - but to elect a new president, and they did so at home in numbers not seen in 14 years. The next election should be about trust, instead it will be about fear Things will not only not get better, but are likely to get worse after May 2015. Independently of who wins the next election, the arithmetics will almost certainly produce a Tory or Labour-led government, and the gap between popular vote and seats - the difference between what voters want and what voters get - is likely to widen to unprecedented levels. Everything appears to be changing in British politics, except those at the top of the political establishment. Hardly a trust winning formula, and one that won't make voters too happy come the morning of 8 May 2015.
