"I vote Conservative, because I think they will keep the economy on track and I think any other solution will cause the problem for the economy," Nick, 50, told Sputnik on Thursday.
Ariel, 20, also praised the economic contribution of the Conservatives, stressing that under the Tory-led government the country "went into the best position in terms of our economy, and I think they have done good job so far, creating more jobs, increasing our GDP."
The Labour's pledge to help people and be on their side is also yielding results for the party.
"I voted Labour because I don't like to see the Tories dismantling our welfare state and I think the Labour Party cares more for people," Theresa, 65, told Sputnik as she left the polling station.
"Labour, of course. It is important. I don't think you can live in this area and be a normal person and don't realize that Labours are always on your side," 29-year-old Caroline said.
Outside of London, the two main parties face competition with those political forces that provide the alternative.
Barney, 38, a full-time father in Bristol, said the Green Party promised a change to the UK politics, pushing the two-party system to include other viable forces.
Scott, a solicitor from the United States who has been living in Britain for 15 years, compared the disillusionment with the two-party system in the United Kingdom to that in the United States.
"The disillusionment with the two-party system here is as strong as it is in America. People see both parties as part of the establishment and there is not much of difference between them, there is a great deal of contempt for both, neither party is hoping to make that much of a change, and they are both corrupt," Scott told Sputnik, adding that smaller parties were offering different ideas.
On May 7, British voters elect representatives to sit in the House of Commons until 2020. Traditional leaders — the Conservatives and the Labour — are predicted to receive about one third of the ballot each. Anti-immigration UK Independence Party (UKIP) party comes third in the popularity ratings.
