After the first major television debate and interview of the British election campaign, a poll published on Friday showed headline support for the Conservative and Labour parties was unchanged. A Survation poll carried out since Thursday night's debate showed the opposition Labour Party on 33 percent and Prime Minister David Cameron's Conservatives on 31 percent, both unchanged since a similar poll on March 25. The poll also showed a boost in the approval ratings of Labour leader Ed Miliband by 8 percentage points since a pre-election television interview and debate. "These two events have been a real boost for Ed Miliband," Damian Lyons Lowe, the chief executive of the Survation pollster, said in an emailed statement. http://english.ahram.org.eg/News/126829.aspx
