Gordon Brown has said sorry for offensive e-mails sent by one of his closest advisors that targeted leading members of the opposition.The Conservative Party has been demanding a personal apology from the British Prime Minister since the personal attacks emerged last week. “Well, I’m sorry about what happened. I’ve said all along that when I saw this first I was horrified, I was shocked and I was very angry indeed. I think the most important thing that we do is reassure people that everything is being done to clean up politics in our country.” The advisor at the centre of the storm, Damian McBride, resigned soon after the e-mails were leaked. He had proposed publishing scandalous but unfounded stories about the private lives of leading Conservatives on a blog linked to Brown’s ruling Labour Party. It is seen as an embarrassment for Brown, who had promised to rid British politics of sleaze and the so-called “dark arts” after assuming power from Tony Blair.
