One of the most piquant features of the British Parliamentary voting system is that it is so well established and so well analysed that pundits can predict with a high degree of accuracy which MPs will lose their seats for any given % swing of opinion against the government at the next election.

Thus the current group of Labour MPs are staring at the opinion polls in horror, as so many of them stand to be Out next time round if things carry on as they are.

Thus the Labour ship heads boldly for the rocks. At what point do the crew rebel and heave the captain overboard?

Robert Mugabe of course sets Gordon Brown a magnificent example in full steam ahead political navigation when rocks are looming.

Robert. Gordon. Names of great richness in Scotland.

Are these two leaders by some chance related?
