Planned to coincide with the five-day annual World Economic Forum, the Great British Tea Party in Davos, Switzerland, was looking forward to Jagger’s appearance, saying No. 10 Downing Street was “tickled pink” to have the rocker among its guests. It was to be the first time Jagger would appear at an event for a conservative prime minister, according to London newspaper The Sun.

“Mick Jagger is a massive international celebrity who seldom has anything to do with politics,” an unidentified source told The Sun, adding, “So it’s fantastic that he’s agreed to help the P.M. sell Britain to the world in this very special year.”

But that was this morning in London. Since then, reports indicate Jagger has changed his mind.

“During my career I have always eschewed party politics and came to Davos as a guest, as I thought it would be stimulating … I have always been interested in economics and world events,” Jagger, who once attended the London School Of Economics, said in a statement, according to Reuters.

“I now find myself being used as a political football and there has been a lot of comment about my political allegiances which are inaccurate. I think it’s best I decline the invitation to the key event and curtail my visit.”

Jagger’s remark about people speculating on his “political allegiances” may have been a reference to this morning’s Sun article, which noted his mother Eva was “an active member of the Tory Party” and that Mick himself is suspected of being ”a closet Conservative supporter.”

But even with Jagger bowing out of the event, the Great British Tea Party’s guest list isn’t exactly short on celebs. Also appearing is World Wide Web inventor Sir Tim Berners-Lee, who might be considered a rock star in his own right.
