MPs have written to the Competition and Markets Authority (CMA) requesting more information about its proposed scrutiny of the Sainsbury’s/Asda deal, the Financial Times (£), The Times (£) and most other news outlets report. They expressed worries about the impact of the deal on the competitiveness of suppliers and on consumer choice in particular locations. They asked five questions about the timing, length and scope of the probe and for an explanation of the criteria the CMA would use to determine an acceptable distance between stores belonging to the new combined business, as well as the tests that would be used to decide whether there should be disposals to competitors or other companies. The Daily Telegraph says the letter was signed off by MPs on two parliamentary committees – the Business, Energy and Industrial Strategy and the Environment, Food and Rural Affairs committees. Neil Parish MP, chair of the environment committee, wrote: “I am concerned that with two supermarkets [Tesco and the merged Sainsbury’s/Asda] taking up around 60 per cent of the market, suppliers would be more reluctant to raise complaints about unfair practices.” Business committee chair Rachel Reeves MP said: “The CMA needs to be a champion of consumers and must look closely at the impact of this merger on the supply chain as well as the effect on competition”, The Daily Mail. The Guardian says the CMA has already said it is likely to review Sainsbury’s deal with Asda but declined to comment in advance of an inquiry opening.

A CMA “no” to a combined Asda/Sainsbury’s will see shoppers pay the price, The Daily Telegraph reckons. Shadow business secretary Rebecca Long-Bailey claimed in a Radio 4 interview the deal risked suppliers being squeezed, workers laid off and shoppers facing high price – all at the same time.

The Times (£) is upbeat for Sainsbury’s shares and rates them a “buy” noting that with improving profits and at least a year or more before “Sasda” happens, there are share price gains to be had.

An opinion piece in The Daily Mail states the obvious – “Sainsbury-Asda deal would create a supermarket Goliath capable of dictating prices”. The article concludes consumers, suppliers and staff will end up bearing the costs.

What is a supermarket, asks The Times (£) in an opinion piece which wonders whether the industry that the CMA will investigate is about to be disrupted by a new entrant from Silicon Valley, pointing out that the laws that determine our approach to monopolies date back decades, and in the case of the US, more than a century.

Lidl is selling locally grown cannabis to Swiss shoppers in the form of two products derived from hemp flowers as an alternative to rolling tobacco, reports The Guardian. Lidl’s products are designed to provide a relaxing and anti-inflammatory effect, but not to be intoxicating, the newspaper says.

Swiss supermarket chain Coop - unrelated to the UK brand - was the first to sell cannabis cigarettes last year.
