The Government is facing renewed calls for a full inquiry into the Iraq war following the release yesterday of the first draft of the notorious dossier on Saddam Hussein’s weapons of mass destruction.

The 30-page draft – drawn up by the Foreign Office’s then-communications director and former Sunday Mirror political editor John Williams – was released after the Government lost an appeal last month against a ruling that it should be disclosed under the Freedom of Information Act.

The document was not released to Lord Hutton’s inquiry into the death of Government weapons expert, Dr David Kelly, as the Government argued that it was not relevant to the investigation.
