The UK's decision to give the Chinese telecoms equipment maker partial access to its 5G network risks trade retaliation from the US. But a decision to exclude Huawei altogether might have risked infuriating China.

Ed Butler looks at the actual technical hurdles to making 5G broadband networks secure from foreign snooping with the help of BBC technology reporter Zoe Kleinman, and analyst Emily Taylor of Oxford Information Labs.

Plus Norbert Ruttgen, chairman of the German parliamentary committee for foreign affairs, explains why he believes his own nation should stand strong and not succumb to the threat of foreign trade retaliation when making decisions about national security.
