The big corporate news this morning is a 3.7% slump in like-for-like Tesco sales for the three months to 24 May. The third successive quarter of worsening sales.
"The first quarter," said the company, "has also seen a continuation of the challenging consumer trends in the UK, reflecting still subdued levels of spending in addition to the more structural changes taking place across the retail industry."
In that last clause Tesco means the nibbling away of its market share by Aldi and Lidl, a structural change, as Tesco admits, likely to be long term. Including international sales group sales growth dipped 0.9%.
At time of writing Tesco's share price was 297.45p - a 23% fall from its 386.40p year high.
