Second poll gives Cameron's Conservatives 4 point lead over Labour

LONDON (Reuters) - The Conservative Party took a 4 percentage point lead over the opposition Labour Party in a Comres poll published on Thursday ahead of a May 7 election, hours after another poll gave David Cameron's party the same lead. The poll for ITV and the Daily Mail put the Conservatives on 36 percent, up 2 percentage points, and Labour on 32 percent, down 1 point. The UK Independence Party (UKIP) was down 2 points to 10 percent, the Liberal Democrats down 4 points to 8 percent and the Greens up 1 point to 5 percent. 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 typical 3-percentage-point margin of error. Opinion polls have consistently shown that neither the Conservatives nor Labour are likely to win an overall majority in the 650-seat Parliament. (Reporting by Kate Holton; Editing by Andrew Osborn)
