What exactly will Brown announce?

So Gordon Brown is in Iraq this morning. According to the Times, this is

to set an end date for Britain's mission in Iraq, announcing all but a handful of troops will be home by next summer.

Mr Brown thanked UK troops and declared Britain's mission in Basra complete.

The 4,100 troops stationed in Iraq will start to return home in March.

According to the Indy, Brown and the Iraqi PM Nouri Maliki said:

"The role played by the UK combat forces is drawing to a close. These forces will have completed their tasks in the first half of 2009 and will then leave Iraq."

So will Brown announce that an inquiry will start when the combat troops are home? Not one of the papers has yet asked this question.
