(Reuters) - British Prime Minister David Cameron's Conservatives have a one percentage point lead over opposition Labour Party in the run up to Britain's general election, according to a YouGov opinion poll for the Sun newspaper published on Wednesday.
The poll ahead of the May 7 election showed Conservatives at 35 percent, up one point from Tuesday, versus Labour at 34 percent, down one point, polling company YouGov said.
The two main parties have been neck-and-neck in most opinion polls since the start of the year, with neither establishing a sustained lead exceeding the 3-point margin of error.
Opinion polls have consistently shown that neither of the two main parties is likely to win an overall majority in the 650-seat Parliament.
