The UK is over-reliant on a small number of big tech companies to provide critical data centres, software and digital infrastructure, placing national security at risk. A report by the Open Rights Group, which is backed by a number of MPs warns the UK’s dependency on US big tech companies places the UK at risk as relations between the two countries have become strained. Rifts between the UK and the US over the conduct of the US and Israel’s war with Iran, if they are exacerbated, could expose the UK to threats of US sanctions that could impact critical infrastructure, the report warns. Big Tech companies have used their power and resources to control markets, limit innovation and lobby government, allowing them to capture the market for UK’s critical infrastructure, the lobbying group claims in a report published today.
