Defeat in a vote of confidence would mean a General Election (which makes it a bit like turkeys voting for Christmas), Gareth, but it wouldn't remove Blair as Party Leader going into the Election. Unless he chose to resign.

And what can Labour Party members who aren't MPs do in any case? It was suggested up the thread that in theory a card vote of no confidence could take place at the Party Conference - but that would never be allowed to be put to Conference these days.
