First the Europe debate and now attempts to block equal marriage.
They are part of a coalition government that is in a vulnerable position, that is languishing in the polls with high unemployment and a stagnant economy.
So they decide this would be an ideal moment to rock the boat over their old favourite topic; the EU, a topic quite a way down most voter's priorities.
Not only that, but now they are attempting to derail, the equal marriages act, a piece of legislation that commands majority support from the public and parliament.
Did they learn nothing from the landslide that wiped them out in 1997? Plotting, disloyalty and sabre rattling over Europe made them unelectable for over a decade, Have they got such a taste for Hari Kari that they are prepared to do all that again over their own personal prejudices?
As a Labour party supporter I should be beside myself with glee, but curiously I am not. Obviously I want Labour government, but I also want a coherent opposition party of the centre-right to hold them to account, rather than a ragbag of extreme right wing malcontents and provincial bigots.
