A debate is about to begin in the House of Commons over the possibility of military action against the Syrian regime.
This morning the government has published three documents relating to Syria, in an attempt to win over support for action.
The first is a summary "letter" (studiously avoiding the word "dossier", which is linked with Tony Blair's "dodgy dossier" legitimising the Iraq War), which notes that at least 14 attacks have been launched by the Assad regime using chemical weapons since 2012.
The second is a document outlining the government's stated legal position for potentially launching an offensive against the Syrian regime, if it comes to that.
It notes that a UN Security Council resolution will be sought initially, but that if it fails there would be a legal basis to go it without UN approval anyway.
MPs will be debating two motions: one tabled by the Conservative government, one by the Labour opposition.
The two sides disagree over how to proceed against Syria. The government appears to be committed to action with or without UN backing; Labour has said it will vote against that, the AP report. Therefore it has tabled its own opposition motion, with more nuanced language.
