Her Majesty’s Official Opposition is the party with the most seats in the Commons that is not in Government. If Labour splits in two, the faction with the most seats would become the Opposition – and if both factions have more than 54 MPs, they would also knock the SNP into fourth place, causing the nationalists to lose most of their Parliamentary privileges (and making EVEL debates that much more important). The different factions from Labour would also have to vie over the £5m+ of short money it currently receives every year – and, awkwardly, it would probably need a motion put forward by the Government to redistribute the cash. That awkwardness would be nothing compared the wrangles over staff, property and debts, though. In short, this extraordinary political era is not going to calm down for a while yet.
