I am not in the front rank when it comes to demanding additional cash, but there is one aspect of policy on which a small amount could go along way. Our troops in Afghanistan are serving alongside American troops in an area that the United States Government have defined as a hostile fire zone. The Americans get a complete income tax exemption during the time that they are serving in a hostile fire zone. Does my hon. Friend agree that the Government should match those terms? It would not cost much in public money, but it would go some way to showing this country's appreciation for our service men, who do so much for us.
