A former director of concrete manufacturer Stanton Bonna Concrete was given a two-year suspended prison sentence and made the subject of a six-month curfew order for his role in price fixing and market sharing arrangements in the supply of precast concrete drainage products. 

Barry Cooper was also disqualified from acting as a company director for seven years. Mr Cooper was arrested in 2013 at the start of an investigation by the Office of Fair Trading, the CMA’s predecessor. In March 2016 he pleaded guilty to one count under section 188 of the Enterprise Act 2002, the criminal cartel offence. The CMA continued the criminal investigation but decided, in June 2017, that there was insufficient evidence to charge any further individuals with the offence.

In April 2016 the CMA also launched a civil probe into whether businesses in the sector have infringed the prohibition on anti-competitive arrangements (under Chapter I of the Competition Act 1998). This investigation continues. The CMA is expected to decide whether to proceed with the investigation later this month.
