UK 'to send more troops to Iraq'

(That's the current headline but the BBC tends to change it as news develops)

Defence Secretary Geoff Hoon is to make a statement to MPs later on Thursday about the deployment of British troops in Iraq, the Ministry of Defence says.
The MoD says he will give details of adjustments to numbers of troops in the area of Iraq under British control.

Mr Hoon will make the announcement in the House of Commons at about 1315 BST.

A well-placed defence source told the BBC the net change to the size of Britain's military deployment will involve an increase of "around 400".

I just heard him speak and it sounds more like a rotation than added forces.
