Six lords* are in Gordon Brown's cabinet and I believe this is the highest number of unelected cabinet members since the 1960s, possibly earlier. Please feel free to correct me!
Now you could well make the argument that, like the USA, the great leader should be able to pick the best talents above those which political parties and electors have chosen. But that's hardly been debated here, Brown has just slipped into this position due to the lack of talent for him to pick from.
It's a rather shocking position for Labour to be in.
