Just thinking back to the george Galloway rumpus, I yesterday watched the House he is paid to serve in, The House of Commons, during Prime Minister's Question Time. This morning whilst getting dressed, I watched the house he is now in, the Celebrty Big Brother House.
My conclusion is that the differences are very small. Both seem to be full of attention seekers whose conduct is well below the standard of the average playground.
Th transfer from one to the other cannot be very difficult.
