George Michael has criticised the British media and the country's political system in a series of messages on Twitter.

The singer took to the social networking website to express his dismay at the current Leveson inquiry into media ethics, something which he said he was asked to appear at.

He opened: "It's interesting don't you think, that not one newspaper went near the things I said in defence of gay teenagers last week. Those gay loving people at the Daily Mail should be admired for their consistent attitude to me. Not a word about those poor kids...But I gave them another chance to have a dig at me just by joking a little about my past. They really are pathetic, pitiful human beings."

He continued: "[Rupert Murdoch] has been called 'unfit' to run a major media company by MP's. Understatement of the year? And it's so funny that the Conservatives in government are defending him! Trying to cover their arses when those lily white buttocks...of theirs are already on display for the whole world to see. Cameron must be the most cowardly PM we've seen for decades. One last thing... I was asked to talk to the Leveson inquiry, but I declined. It's all bulls**t."
