PM must resign, for Negligence or for Lying to Parliament
Forget the dossiers. This is a much more serious issue.
If Mr Blair really was sure that Saddam could not strike Cyprus, Europe or neighbouring countries with WMD when he launched the invasion, then he lied to Parliament yesterday by saying that he didn't know. The rule is if you lie to Parliament, you resign. If he really didn't know, and didn't even bother to ask, then he must resign on the grounds of incompetence or, more appropriately, Criminal Negligence.
There is a third possibility, that he really believed Saddam could strike British bases in Cyprus or other long range targets with WMD. Along with this is the possibility that he believed the invasion force could be hit with WMD. In a way, this is the worst of all possibilities. It shows reckless endangerment of troops who didn't even have the right equipment to defend themselves, for one thing.
Oh what a tangled web we weave,
When first we practice to deceive.
Greg Dyke should take his case to an Industrial Tribunal, receive compensation and be re-instated. The real culprits in this affair should be put on trial.
