Thursday 17 December 2009 - the plan so far
Mark Urban returned from Afghanistan last week having spent time with the US marines operating in Helmand.
Mark was with the marines as they fought to seize back control of the town of Now Zad from insurgents - he wrote about this in his blog while he was there.
And tonight, we will be broadcasting the film Mark has made on his time embedded with the troops.
We are also looking at the Copenhagen climate summit, MPs' expenses and British Airways.
More details later.
