Simple really. You lie to the HOC come up with a dodgy dossier of spurious claims about the Iraqi capability to fire nukes (where are those pesky missiles again drat, is Tony STILL playing hide and seek in the desert?) oh yeah, and bump off the poor bloke who risks exposing your pack of lies.
A non binding vote on what the opening position at negotiations was always going to end that way. There will be a budget freeze, the budget term will come down to 5 years and the HOC will pass it.
Steddy Eddy will try a make the government look as bad as possible to get back in, but where does he stand on Europe again? Seems to me like he is pissing on his own picnic.
