Question to the HM Treasury:

To ask the Chancellor of the Exchequer, if his Department will make an assessment of the (a) prevalence of the use and (b) reliance on the supply of Chinese-made cellular internet of things modules in the UK's finance infrastructure.

The UK takes its national security extremely seriously, including the security of its critical infrastructure and all sectors of the economy. We encourage all organisations to follow National Cyber Security Centre and National Protective Security Authority supply chain security guidance when selecting a technology supplier. This guidance sets out the considerations that organisations should be making during the procurement process.

For the finance sector, the Bank of England, the Prudential Regulation Authority and the Financial Conduct Authority have set clear expectations for how regulated firms should manage the risk posed by third parties.
