British Prime Minister David Cameron speaks during a campaign visit in Frinton-on-Sea, Britain April 24, 2015.
The figures, gathered by the UK-based market research company, show David Cameron and the Conservatives on 35%, whilst Labour are behind on just 30%.
The five point lead will provide a boost to the Prime Minister, given that the two main parties have been neck-and-neck in the other polls in the run up to the May 7th election.
However, you have to be cautious in interpreting the importance of a single poll. As it stands, it's still highly unlikely that any of the major parties are going to win a majority in Parliament.
The poll also shows UKIP with a two point lead over the Green Party and the Liberal Democrats who both lag behind on eight percent.
Another poll published today by YouGov also sees the Conservatives infront of Labour, but by a modest one point which is more in keeping with previous poll-of-polls trends.
