BASRA, IRAQ - OCTOBER 18: People gather around a Land Rover as it arrives at the village Al Houta on October 18 2008 near Basra, Iraq. The trip by the 51 Sqn Royal Air Force Regiment Force Protection Wing was part of a 'key leader engagement' (KLE) visit to the village close to the Basra Airbase to recruit local labour and engage with the village shiek. Visits of this type are seen as key in efforts to continue winning the support of the local Iraqi population. Although improved security in the region has brought some benefits such as improved trade and commerce, much of the infrastructure remains in a poor state of repair. Britain's Prime Minister Gordon Brown has indicated that the number of UK troops could be scaled down - especially as the security situation in the south of the country continues to improve.
