The H&H letter contains a glaring admission of a Party in disarray: "As we move towards a General Election it remains the case that the Parliamentary Labour Party is deeply divided over the question of the leadership ... The continued speculation and uncertainty is allowing our opponents to portray us as dispirited and disunited."
Battered Brown looks set to weather the storm and cling on until the bitter end. But a failed coup bid leaves a wretched Party deeply divided with a PM hostage to his own cabinet.
Downing Street will be busy hatching cunning plans to come out fighting with a 'united' front.
But an unelected leader who cannot command the unswerving support of all his parliamentary MPs and ministers in the run up to a general election confirms what voters already know. A Party 'dispirited and disunited' with a lame duck prime minister of a fag-end government.
As the Tories sit back and watch the New Labour sport of tearing itself apart, Cameron's campaign slogan springs to mind: We can't go on like this.
