Earnings results continued to pour in last week with retailers Carrefour, Delhaize and Waitrose amongst those issuing sales and profit figures. Delhaize told analysts there was work still to be done in the US, while Carrefour insisted it has to invest in order to build on signs of improvement. Elsewhere, Vion was bought by Boparan Holdings, and a BBC investigation uncovered evidence of horse smuggling from Ireland to the UK.
