Sorry nothing else will do.
The Guardian reports:
Pressure is growing on David Cameron to identify the mystery Tory MP who deliberately scuppered a landmark anti-poverty bill that could have stopped "vulture" bankers profiteering from the developing world's debt burdens.
Debt campaigners have reacted in fury and disbelief to the killing of the bill and Labour MP Sally Keeble, one of the bill's backers, has accused the Conservatives of "duplicity" by pretending to back the legislation and then sabotaging it at the last minute.
That's blood on Cameron's hands - especially as it is thought that Tory whips did this.
In the circumstances to call them bastards is polite.
