This is more like Major's nosedive than Thatcher's fall

Blair's government has the hallmarks of the Tory administration in
1995, with Iraq Labour's Europe. He has ceased to govern

The prime minister tells the Labour party to stop playing petty
politics and let him get back to governing the country. The distinction
he makes between petty politics and governing is real, but he draws the
wrong conclusion. The atmosphere of decay around government is
unmistakable. He still has room for manoeuvre in the sphere of petty
politics, but his days of real governing are over. What lies before
Tony Blair is a period during which Labour party politics will dominate
his scene as he tries to organise a graceful exit.
