's business improvement director Noel 'Bob' Robbins has stepped down after almost 40 years at the retailer.His departure follows the announcement of several redundancies at Tesco's senior management.
Since joining in 1975, Robbins has held a number of roles at Tesco including chief executive of Asia and head of Central Europe.
In 2012, Robbins controversially sold shares worth £202,000 a week before last year's shock profit warning, making an extra £40,000.
Tesco said that it had been 'confident' that Robbins had not had access to any price-sensitive information and that the sale had been approved in the usual way.
