When exactly?

It's hard to make any sense of this Guardian article, which says that

Gordon Brown will consider holding an inquiry into the Iraq war once British troops have returned home, government sources confirmed yesterday.

This is exactly the confused position that Brown articulated - if that is the right word - in December. That is a backtracking on Brown's promise to hold an inquiry when the troops come home, not merely to consider it. What the article doesn't say is whether this means all British troops or just the "combat troops" who are due home in the next few months.

It still looks like an attempt to move the goalposts.
