Huawei's expulsion from the UK's 5G network is the latest development in a growing US-China cyber cold war - but Beijing has bigger plans afoot.

Cyber-security consultant Dominique Lazanski explains how the Chinese authorities are proposing to replace the data protocols that underpin the current flexible, open internet with ones that would enable national governments to exert much greater top-down control within their borders.

Meanwhile US President Trump continues to focus his ire on telecoms equipment maker Huawei, and major Chinese tech firms. Laurence Knight gets the latest from the BBC's Asia business correspondent Karishma Vaswani. Plus, Justin Sherman of the Atlantic Council think tank in Washington DC fears that if the US doesn't start working with other democracies, then the free, open internet we have grown up with may struggle to survive.
