MEGA-RICH Asda bosses have pocketed a whopping £1.4 billion in petrol profits while condemning their staff to low pay, GMB charged today.

The retail union has written to Asda owners Zuber Issa and Mohsin Issa to demand an urgent meeting after another of the brothers’ firms - EG Group - recorded a 20 per cent jump in gross fuel profits.

Despite the mammoth increase, brought on by surging global energy prices, Britain’s third biggest supermarket is “once again the worst paying of the big four,” GMB said, the others being Tesco, Sainsbury’s and Morrisons.
