A number of celebrities are currently searching for a new cause.
Bluefin Tuna is declining as a source of publicity and the 'environment' is evidently no longer sustainable as a utility for self-promotion.
A spokesperson for the celebs said, "We have noted that the 'stock' of MPs is down right now and we think that the time might be right to stand in front of cameras on Westminster Green and show how worried we are about democracy."
"It is also evident that once a celeb has done acting, done singing, done novels, climbed Everest and done pretty well everything else known to man, the only thing left is to stand for parliament."
