Supermarkets are preparing to introduce rationing for online shoppers to prevent panic buying in the event of a no-deal Brexit, The Sunday Times (£) has revealed. Sainsbury’s has begun drawing up plans to restrict the quantities of some goods that can be ordered online in an effort to stop consumers stockpiling. The plans have been decided amid claims that supermarkets’ food stocks could be depleted within just four days – with shoppers facing almost empty shelves within five days of a no-deal Brexit. “With limited storage space, online rationing is among a number of measures that are being considered to help mitigate the effect of a no-deal Brexit,” a source familiar with the plans said.

Marks & Spencer is under mounting pressure to slash prices in order to stop the rot in its food business (Daily Mail). The high street stalwart plans to open new superstores to try and bring families in for the big weekly grocery shop – pitting M&S against the likes of Sainsbury’s and Tesco. It will also start selling its food online for the first time next year after it bagged a £1.5bn deal with online food delivery company Ocado.

A massive bonus scheme which could see Ocado boss Tim Steiner pocket up to £100m is ‘excessive’ and should be rejected by shareholders, according to an influential investor group. The payouts, revealed by The Mail on Sunday, are based on the online grocer boosting its share price over the next five years. Steiner’s payout is capped at £20m a year and four senior executives could each get a maximum of £5m a year.

Sainsbury’s has hit back at the competition regulator’s adverse provisional findings on its proposed merger with Asda, accusing it of making basic mathematical errors and of issuing flawed and inconsistent results (The Times £). In its response to the Competition & Markets Authority’s report, Britain’s second largest grocer says that the regulator made a series of mistakes. It claims the CMA has “double-counted” Asda convenience stores and incorrectly counted Asda Living stores, which typically are 33,000 sq ft and do not sell grocery items, as convenience stores.

KPMG, the administrator for scandal-hit café chain Patisserie Valerie, has revealed that its forensic accountants found a £94m black hole, more than double the previous £40m estimate (Telegraph £). In its latest report the accountancy firm said Patisserie Valerie, which collapsed into administration in January, falsely claimed to have £54m in cash and that its assets were valued £23m higher than they were. The company plunged into administration after it was unable to secure new bank finance following the discovery of “potentially fraudulent” accounting irregularities (The Guardian). Accounts produced for Patisserie’s management last August showed net assets of £108m when in fact the company had assets of only £14m and implied trading losses of £21m, according to KPMG (The Times £).

Patisserie Valerie shareholders are threatening to take the collapsed chain’s administrator KPMG to court to get hold of a devastating report alleged to show how the company’s cash balances were artificially inflated (Telegraph £).

Discount retail giant B&M Bargains is attempting to wriggle out of strict rules designed to stop major chains exploiting food and drink suppliers (Daily Mail). The company, which has about 600 stores and annual sales of £2.6bn, claims a decision to force it to sign up to the Groceries Code Adjudicator would lead to ‘irreparable financial harm’. GCA rules ensure that major companies make timely payments to suppliers and that the correct procedures are followed when contracts are terminated.

‘Tesco’s Dave Lewis finds his discount dream is not all right, Jack,’ write Sam Chambers and Liam Kelly in the Sunday Times (£). ‘Lewis has committed to opening 15 stores within the first year, but after eight were opened in the first three months, none have been opened since. Tesco said more stores would be opened in the coming months and that customer feedback so far had been very strong.’

The £1bn food giant that runs Domino’s pizza in Britain has been accused of misleading the City over the state of relations with the powerful franchisees who run most of its 1,100 stores (The Sunday Times £). Domino’s Pizza Group, run by former Tesco executive David Wild, received a letter from a group of angry store owners last week. It warned that comments suggesting a resolution to an ongoing dispute could be found were ‘extremely misleading’, because Wild and the board were ‘at total odds with the franchisees’.

Prestat, the UK chocolatier said to be an inspiration for Roald Dahl’s book Charlie and the Chocolate Factory, has been bought by Italian coffee and chocolate dynasty Illy (Financial Times £).

‘Northern Irish farmers are urging the DUP to back May’s Brexit deal,’ writes Arthur Beesley in the Financial Times (£).

Rising costs continue to weigh on profit margins at pub operator JD Wetherspoon, after it decided to increase staff wages last year (Financial Times £). The pub group said on Friday that its pre-tax profits had fallen 11% in the six months to the end of January, stripping out exceptional items, to £48.6m. This was in spite of a 7% increase in revenue to £889.6m. The boss of JD Wetherspoon admitted the pub chain had “reached the limits” of its rapid expansion as a higher wages bill hit profits (Telegraph £).

A jump in Italy’s high-quality olive oil prices in the face of a sharp fall in output is proving bittersweet for the country’s olive growers, some of whom have been forced to abandon their farms because of a deadly tree disease and unseasonal frosts (Financial Times £). Italian olive oil prices have surged after production in 2018 more than halved from the previous year to 185,000 tonnes, according to the state-backed Institute of Services for the Agricultural and Food Market.
