Why Huawei's days in the UK could be numbered

The UK government is inching towards taking a decision on Huawei's role in the UK's 5G and fixed-broadband networks.

The National Cyber Security Centre (NCSC) - a branch of the intelligence service GCHQ - has documented all the facts ahead of giving its view. 

And civil servants at the Department for Digital, Culture, Media and Sport (DCMS) are weighing up the financial consequences of ordering a ban or new limits.

In theory, a decision could come as soon as next week but it is likely to take a bit longer.

Those following developments would be forgiven for having a sense of deja vu.

It was only in January that the UK government announced, following a lengthy review, that the Chinese firm could continue to provide equipment and expertise to the UK networks, albeit with a new cap on its market share.

Washington has continued to assert that Huawei poses a national security risk - most recently claiming it is either backed or owned by Chinese miliatary - something the firm denies.
