UK Probes Defence Contracts for Bid-Rigging With Data Tools

The UK's Competition and Markets Authority (CMA) is intensifying its fight against bid-rigging in public procurement, proposing to use data analytics to scrutinize Ministry of Defence (MoD) contracts. The initiative reflects the CMA's view that tackling collusion is a key priority, especially within the UK's £400 billion public purchasing market. The agency plans to expand the use of its Bid Rigging Intelligence Tool (BRIT) to detect suspicious patterns, and it is calling for the mandatory, centralized collection of bid-level data—including from losing bidders—to make this screening effective. For government contractors, particularly in the defense sector, this signals a significant increase in enforcement risk. The consequences for cartel conduct are severe, ranging from heavy fines and director disqualifications to potential criminal prosecution and, crucially, mandatory debarment from future public contracts under the new Procurement Act 2023. Counsel should advise clients in this space to anticipate heightened scrutiny and ensure their bidding practices and compliance programs are robust.
