The last poll before May 7 elections suggests that Britain’s main political parties, Labour and Conservative, remain neck-and-neck.

According to a YouGov opinion poll, both the Tories and Labour have gained one-point since Tuesday, tying on 34%.

The poll also puts the Liberal Democrats on 9% which is one point less than Tuesday's data. It shows the UKIP has also lost one point to stay on 12%. The rest of the parties have racked in 11% of the votes-one up compares to Tuesday's figures.

Thursday’s vote is seen as the most unpredictable election in recent decades.

With neither party able to win an overall majority to form a government, Britain is heading towards a hung parliament amid rising concerns over uncertainty about the country's future in the European Union as well as its economic policy.
