Businesses and the finance sector must bear the burden of cyber security for the consumer, the head of Britain's GCHQ spy agency will tell a Glasgow conference today.

Jeremy Fleming will call on companies to work clossley with intelligence officials secure the internet.

It comes after the Daily Telegraph today reported Theresa May has given Chinese firm Huawei the green light to work on Britain's new 5G network, despite security concerns.

An intelligence source later told Reuters that Huawei would be blocked from all core parts of the 5G network and only have restricted access to non-core parts of it.

In extracts of a speech to be given at the CYBERUK conference, Fleming said the signals intelligence agency would cooperate closely with manufacturers, internet service providers, online platforms and banks to "take the burden of cyber security away from the individual".

The latest incarnation of the internet has enabled innovation and technological breakthroughs, Fleming said, but also brought "new and unprecedented challenges for policymakers as we seek to protect our citizens, judicial systems, businesses - and even societal norms."

Western governments including Britain are pushing businesses and the public to take more precautions online and guard against threats posed by cyber criminals and nation state hackers.

The CYBERUK conference, hosted by GCHQ's National Cyber Security Centre (NCSC) at the Scottish Event Campus, will also mark the first time senior officials from countries in the Five Eyes intelligence-sharing group - Australia, Britain, Canada, New Zealand and the United States - have hosted a public panel discussion.

NCSC head Ciaran Martin said: "Cyber attacks do not respect international boundaries, and many of the threats and vulnerabilities we face are shared around the globe. "Each nation has sovereignty to defend itself as it sees best fit, but it's vital that we work closely with our allies."
