BBC News By Zoe Kleinman image copyrightGetty Images It's not just the unseasonally cold weather that's creating a somewhat chilly climate for Huawei's UK operations. It's been banned from the UK's 5G infrastructure and it faces ongoing scrutiny from the National Cyber Security Centre over its security practices, and whether it has links with the Chinese government, which it denies. On a consumer level, its handset sales have plummeted all over Europe since the US introduced a trade ban, which makes them incompatible with essential Google apps, including Gmail, Google Maps and the Play Store. And yet while you or I might have got our coats and left by now, Huawei remains. Not only is it still here, it's still investing in the UK - creating jobs, and funding university research.
