Huawei in charge of TalkTalk's net filtering
The BBC has revealed that TalkTalk's net filtering system, which blocks millions of web addresses and has been praised by Prime Minister David Cameron, is being controlled by Chinese networking giant Huawei.
Huawei has come under scrutiny in recent months after being blocked from doing business with the US after allegations that it has links to the People's Liberation Army in China and that ultimately any Chinese company is subject to the Chinese government.
