Difficult questions
Last month Britain handed over command in Helmand to a US general.
Maj Gen Richard Mills, of the US Marine Corps, assumed control of all Nato-led International Security Assistance Force (Isaf) troops in Helmand on 1 June.
Dr Fox is expected to announce Britain will concentrate on Helmand's busy central belt, leaving the north and south to the US.
The BBC also understands that more British troops will be sent to Helmand to help with the redeployment.

British troops in Afghanistan are to hand over responsibility for the Sangin area of Helmand province to US forces, the BBC understands.
The UK has suffered its heaviest losses in the area with 99 deaths since 2001.
British Defence Secretary Liam Fox is expected to tell MPs the move could happen by the end of the year.
The military insists the move is a redeployment, now there are more US troops on the ground, but the Taliban are certain to portray it as a defeat.
