Could an item in The Spoof have resulted in IDS's resignation? No, probably not, but let's take a look at the "facts" of the matter.
Reacting to the budget, Ian Duncan Smith spoke to The Spoof (disguising himself cleverly as Jan Doodleberg Scmit) and defended the attack on disabled people in the budget. But the experience of seeing this report on the internet shocked him into realising that the Government had gone too far in its persecution of disabled people.
The staffroom at The Spoof was woken from its customary afternoon nap by a call from Smith (alias Scmit) advising the only reporter awake at the time, the redoubtable political reporter Joe Wank, that our piece had 'brought him to his senses'. He cried that he didn't want to be compared to Nazis. He felt the nasty Party could not be thought of as the Nazi Party if caring Conservatism was to survive.
Clearly the spoof in The Spoof had spooked the Minister - or ex-Minister as he was becoming.
