British Prime Minister David Cameron said on Tuesday an internal review had shown the government needed to enhance its oversight of a cyber security centre in southern England run by Chinese telecoms firm Huawei. Huawei supplies software and equipment which channels phone calls and data around Britain, but has found itself at the centre of a debate, particularly in the United States, over whether it is a risk for governments to allow foreign suppliers access to their networks. The British government ordered a review of Huaweis cyber security centre in July after parliaments intelligence committee said UK security checks were insufficiently robust when Huawei began working on the countrys network through contracts with companies such as BT in 2005. Cameron said in a written statement to parliament on Tuesday that his national security adviser had concluded the government should enhance its oversight of the Huawei facility and that the GCHQ spy agency should take a leading role in future senior appointments there.
